Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718456, here are decompositions:

17 + 8718439 = 8718456
29 + 8718427 = 8718456
37 + 8718419 = 8718456
79 + 8718377 = 8718456
107 + 8718349 = 8718456
113 + 8718343 = 8718456
179 + 8718277 = 8718456
239 + 8718217 = 8718456

Showing the first eight; more decompositions exist.
