Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625550, here are decompositions:

23 + 8625527 = 8625550
29 + 8625521 = 8625550
41 + 8625509 = 8625550
71 + 8625479 = 8625550
83 + 8625467 = 8625550
191 + 8625359 = 8625550
233 + 8625317 = 8625550
239 + 8625311 = 8625550

Showing the first eight; more decompositions exist.
