Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022770, here are decompositions:

41 + 1022729 = 1022770
131 + 1022639 = 1022770
137 + 1022633 = 1022770
179 + 1022591 = 1022770
197 + 1022573 = 1022770
239 + 1022531 = 1022770
251 + 1022519 = 1022770
257 + 1022513 = 1022770

Showing the first eight; more decompositions exist.
