Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679578, here are decompositions:

79 + 8679499 = 8679578
151 + 8679427 = 8679578
181 + 8679397 = 8679578
199 + 8679379 = 8679578
307 + 8679271 = 8679578
379 + 8679199 = 8679578
499 + 8679079 = 8679578
541 + 8679037 = 8679578

Showing the first eight; more decompositions exist.
