Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942778, here are decompositions:

29 + 942749 = 942778
59 + 942719 = 942778
251 + 942527 = 942778
257 + 942521 = 942778
269 + 942509 = 942778
461 + 942317 = 942778
467 + 942311 = 942778
509 + 942269 = 942778

Showing the first eight; more decompositions exist.
