Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707728, here are decompositions:

17 + 8707711 = 8707728
31 + 8707697 = 8707728
41 + 8707687 = 8707728
59 + 8707669 = 8707728
67 + 8707661 = 8707728
79 + 8707649 = 8707728
97 + 8707631 = 8707728
137 + 8707591 = 8707728

Showing the first eight; more decompositions exist.
