Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626586, here are decompositions:

37 + 8626549 = 8626586
79 + 8626507 = 8626586
127 + 8626459 = 8626586
337 + 8626249 = 8626586
349 + 8626237 = 8626586
457 + 8626129 = 8626586
487 + 8626099 = 8626586
523 + 8626063 = 8626586

Showing the first eight; more decompositions exist.
