Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679880, here are decompositions:

89 + 8679791 = 8679880
113 + 8679767 = 8679880
137 + 8679743 = 8679880
239 + 8679641 = 8679880
263 + 8679617 = 8679880
353 + 8679527 = 8679880
431 + 8679449 = 8679880
569 + 8679311 = 8679880

Showing the first eight; more decompositions exist.
