Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625628, here are decompositions:

29 + 8625599 = 8625628
41 + 8625587 = 8625628
101 + 8625527 = 8625628
107 + 8625521 = 8625628
149 + 8625479 = 8625628
197 + 8625431 = 8625628
269 + 8625359 = 8625628
311 + 8625317 = 8625628

Showing the first eight; more decompositions exist.
