Abstract: We compute Hecke eigenform bases of spaces of level one, degree three Siegel modular forms and $ 2$-Euler factors of the eigenforms through weight $ 22$. Our method uses the Fourier coefficients of Siegel Eisenstein series, which are fully known and computationally tractable by the work of H. Katsurada; we also use P. Garrett's decomposition of the pullback of the Eisenstein series through the Witt map. Our results support I. Miyawaki's conjectural lift, and they give examples of eigenforms that are congruence neighbors.
