Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678812, here are decompositions:

29 + 8678783 = 8678812
53 + 8678759 = 8678812
59 + 8678753 = 8678812
71 + 8678741 = 8678812
113 + 8678699 = 8678812
173 + 8678639 = 8678812
293 + 8678519 = 8678812
419 + 8678393 = 8678812

Showing the first eight; more decompositions exist.
