Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679920, here are decompositions:

37 + 8679883 = 8679920
79 + 8679841 = 8679920
181 + 8679739 = 8679920
211 + 8679709 = 8679920
313 + 8679607 = 8679920
421 + 8679499 = 8679920
463 + 8679457 = 8679920
523 + 8679397 = 8679920

Showing the first eight; more decompositions exist.
