Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659988, here are decompositions:

31 + 8659957 = 8659988
61 + 8659927 = 8659988
67 + 8659921 = 8659988
79 + 8659909 = 8659988
151 + 8659837 = 8659988
241 + 8659747 = 8659988
277 + 8659711 = 8659988
457 + 8659531 = 8659988

Showing the first eight; more decompositions exist.
