Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031788, here are decompositions:

29 + 1031759 = 1031788
47 + 1031741 = 1031788
59 + 1031729 = 1031788
71 + 1031717 = 1031788
179 + 1031609 = 1031788
227 + 1031561 = 1031788
239 + 1031549 = 1031788
257 + 1031531 = 1031788

Showing the first eight; more decompositions exist.
