Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679866, here are decompositions:

127 + 8679739 = 8679866
157 + 8679709 = 8679866
337 + 8679529 = 8679866
367 + 8679499 = 8679866
409 + 8679457 = 8679866
439 + 8679427 = 8679866
487 + 8679379 = 8679866
577 + 8679289 = 8679866

Showing the first eight; more decompositions exist.
