Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620486, here are decompositions:

137 + 8620349 = 8620486
179 + 8620307 = 8620486
197 + 8620289 = 8620486
227 + 8620259 = 8620486
269 + 8620217 = 8620486
353 + 8620133 = 8620486
443 + 8620043 = 8620486
593 + 8619893 = 8620486

Showing the first eight; more decompositions exist.
