Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624486, here are decompositions:

37 + 8624449 = 8624486
103 + 8624383 = 8624486
163 + 8624323 = 8624486
307 + 8624179 = 8624486
349 + 8624137 = 8624486
463 + 8624023 = 8624486
523 + 8623963 = 8624486
547 + 8623939 = 8624486

Showing the first eight; more decompositions exist.
