Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679740, here are decompositions:

31 + 8679709 = 8679740
211 + 8679529 = 8679740
241 + 8679499 = 8679740
283 + 8679457 = 8679740
313 + 8679427 = 8679740
367 + 8679373 = 8679740
463 + 8679277 = 8679740
523 + 8679217 = 8679740

Showing the first eight; more decompositions exist.
