Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625880, here are decompositions:

47 + 8625833 = 8625880
59 + 8625821 = 8625880
71 + 8625809 = 8625880
173 + 8625707 = 8625880
191 + 8625689 = 8625880
239 + 8625641 = 8625880
281 + 8625599 = 8625880
293 + 8625587 = 8625880

Showing the first eight; more decompositions exist.
