Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031790, here are decompositions:

29 + 1031761 = 1031790
31 + 1031759 = 1031790
37 + 1031753 = 1031790
59 + 1031731 = 1031790
61 + 1031729 = 1031790
73 + 1031717 = 1031790
83 + 1031707 = 1031790
113 + 1031677 = 1031790

Showing the first eight; more decompositions exist.
