Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738690, here are decompositions:

19 + 8738671 = 8738690
31 + 8738659 = 8738690
109 + 8738581 = 8738690
151 + 8738539 = 8738690
157 + 8738533 = 8738690
199 + 8738491 = 8738690
241 + 8738449 = 8738690
283 + 8738407 = 8738690

Showing the first eight; more decompositions exist.
