Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612630, here are decompositions:

3 + 8612627 = 8612630
127 + 8612503 = 8612630
151 + 8612479 = 8612630
157 + 8612473 = 8612630
193 + 8612437 = 8612630
283 + 8612347 = 8612630
331 + 8612299 = 8612630
337 + 8612293 = 8612630

Showing the first eight; more decompositions exist.
