Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738790, here are decompositions:

7 + 8738783 = 8738790
23 + 8738767 = 8738790
31 + 8738759 = 8738790
61 + 8738729 = 8738790
79 + 8738711 = 8738790
83 + 8738707 = 8738790
131 + 8738659 = 8738790
149 + 8738641 = 8738790

Showing the first eight; more decompositions exist.
