Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679944, here are decompositions:

61 + 8679883 = 8679944
73 + 8679871 = 8679944
103 + 8679841 = 8679944
337 + 8679607 = 8679944
487 + 8679457 = 8679944
547 + 8679397 = 8679944
571 + 8679373 = 8679944
673 + 8679271 = 8679944

Showing the first eight; more decompositions exist.
