Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625888, here are decompositions:

67 + 8625821 = 8625888
79 + 8625809 = 8625888
101 + 8625787 = 8625888
179 + 8625709 = 8625888
181 + 8625707 = 8625888
199 + 8625689 = 8625888
239 + 8625649 = 8625888
251 + 8625637 = 8625888

Showing the first eight; more decompositions exist.
