Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025788, here are decompositions:

41 + 1025747 = 1025788
47 + 1025741 = 1025788
167 + 1025621 = 1025788
227 + 1025561 = 1025788
251 + 1025537 = 1025788
311 + 1025477 = 1025788
461 + 1025327 = 1025788
509 + 1025279 = 1025788

Showing the first eight; more decompositions exist.
