Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625868, here are decompositions:

47 + 8625821 = 8625868
59 + 8625809 = 8625868
179 + 8625689 = 8625868
227 + 8625641 = 8625868
269 + 8625599 = 8625868
281 + 8625587 = 8625868
347 + 8625521 = 8625868
359 + 8625509 = 8625868

Showing the first eight; more decompositions exist.
