Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679668, here are decompositions:

61 + 8679607 = 8679668
139 + 8679529 = 8679668
211 + 8679457 = 8679668
241 + 8679427 = 8679668
271 + 8679397 = 8679668
379 + 8679289 = 8679668
397 + 8679271 = 8679668
631 + 8679037 = 8679668

Showing the first eight; more decompositions exist.
