Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625610, here are decompositions:

11 + 8625599 = 8625610
23 + 8625587 = 8625610
83 + 8625527 = 8625610
89 + 8625521 = 8625610
101 + 8625509 = 8625610
131 + 8625479 = 8625610
179 + 8625431 = 8625610
251 + 8625359 = 8625610

Showing the first eight; more decompositions exist.
