Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679860, here are decompositions:

19 + 8679841 = 8679860
151 + 8679709 = 8679860
331 + 8679529 = 8679860
433 + 8679427 = 8679860
463 + 8679397 = 8679860
487 + 8679373 = 8679860
571 + 8679289 = 8679860
643 + 8679217 = 8679860

Showing the first eight; more decompositions exist.
