Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680028, here are decompositions:

37 + 8679991 = 8680028
157 + 8679871 = 8680028
421 + 8679607 = 8680028
499 + 8679529 = 8680028
571 + 8679457 = 8680028
601 + 8679427 = 8680028
631 + 8679397 = 8680028
739 + 8679289 = 8680028

Showing the first eight; more decompositions exist.
