Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625490, here are decompositions:

11 + 8625479 = 8625490
23 + 8625467 = 8625490
59 + 8625431 = 8625490
131 + 8625359 = 8625490
173 + 8625317 = 8625490
179 + 8625311 = 8625490
227 + 8625263 = 8625490
257 + 8625233 = 8625490

Showing the first eight; more decompositions exist.
