Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738738, here are decompositions:

31 + 8738707 = 8738738
67 + 8738671 = 8738738
79 + 8738659 = 8738738
97 + 8738641 = 8738738
157 + 8738581 = 8738738
199 + 8738539 = 8738738
331 + 8738407 = 8738738
439 + 8738299 = 8738738

Showing the first eight; more decompositions exist.
