Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679812, here are decompositions:

73 + 8679739 = 8679812
103 + 8679709 = 8679812
283 + 8679529 = 8679812
313 + 8679499 = 8679812
433 + 8679379 = 8679812
439 + 8679373 = 8679812
523 + 8679289 = 8679812
541 + 8679271 = 8679812

Showing the first eight; more decompositions exist.
