Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656984, here are decompositions:

5 + 8656979 = 8656984
113 + 8656871 = 8656984
137 + 8656847 = 8656984
197 + 8656787 = 8656984
251 + 8656733 = 8656984
257 + 8656727 = 8656984
263 + 8656721 = 8656984
293 + 8656691 = 8656984

Showing the first eight; more decompositions exist.
