Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630636, here are decompositions:

37 + 8630599 = 8630636
43 + 8630593 = 8630636
193 + 8630443 = 8630636
367 + 8630269 = 8630636
397 + 8630239 = 8630636
457 + 8630179 = 8630636
463 + 8630173 = 8630636
523 + 8630113 = 8630636

Showing the first eight; more decompositions exist.
