Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679818, here are decompositions:

79 + 8679739 = 8679818
109 + 8679709 = 8679818
211 + 8679607 = 8679818
421 + 8679397 = 8679818
439 + 8679379 = 8679818
541 + 8679277 = 8679818
547 + 8679271 = 8679818
601 + 8679217 = 8679818

Showing the first eight; more decompositions exist.
