Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617982, here are decompositions:

229 + 8617753 = 8617982
283 + 8617699 = 8617982
421 + 8617561 = 8617982
433 + 8617549 = 8617982
463 + 8617519 = 8617982
601 + 8617381 = 8617982
691 + 8617291 = 8617982
811 + 8617171 = 8617982

Showing the first eight; more decompositions exist.
