Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629420, here are decompositions:

11 + 8629409 = 8629420
71 + 8629349 = 8629420
179 + 8629241 = 8629420
227 + 8629193 = 8629420
251 + 8629169 = 8629420
263 + 8629157 = 8629420
281 + 8629139 = 8629420
311 + 8629109 = 8629420

Showing the first eight; more decompositions exist.
