Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697812, here are decompositions:

3 + 8697809 = 8697812
43 + 8697769 = 8697812
199 + 8697613 = 8697812
313 + 8697499 = 8697812
379 + 8697433 = 8697812
433 + 8697379 = 8697812
499 + 8697313 = 8697812
709 + 8697103 = 8697812

Showing the first eight; more decompositions exist.
