Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624636, here are decompositions:

3 + 8624633 = 8624636
19 + 8624617 = 8624636
37 + 8624599 = 8624636
283 + 8624353 = 8624636
313 + 8624323 = 8624636
457 + 8624179 = 8624636
499 + 8624137 = 8624636
577 + 8624059 = 8624636

Showing the first eight; more decompositions exist.
