Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660812, here are decompositions:

59 + 8660753 = 8660812
71 + 8660741 = 8660812
89 + 8660723 = 8660812
113 + 8660699 = 8660812
131 + 8660681 = 8660812
233 + 8660579 = 8660812
269 + 8660543 = 8660812
389 + 8660423 = 8660812

Showing the first eight; more decompositions exist.
