Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626628, here are decompositions:

7 + 8626621 = 8626628
79 + 8626549 = 8626628
211 + 8626417 = 8626628
331 + 8626297 = 8626628
379 + 8626249 = 8626628
487 + 8626141 = 8626628
499 + 8626129 = 8626628
631 + 8625997 = 8626628

Showing the first eight; more decompositions exist.
