Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625748, here are decompositions:

41 + 8625707 = 8625748
59 + 8625689 = 8625748
107 + 8625641 = 8625748
149 + 8625599 = 8625748
227 + 8625521 = 8625748
239 + 8625509 = 8625748
269 + 8625479 = 8625748
281 + 8625467 = 8625748

Showing the first eight; more decompositions exist.
