Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625738, here are decompositions:

5 + 8625733 = 8625738
29 + 8625709 = 8625738
31 + 8625707 = 8625738
89 + 8625649 = 8625738
97 + 8625641 = 8625738
101 + 8625637 = 8625738
139 + 8625599 = 8625738
151 + 8625587 = 8625738

Showing the first eight; more decompositions exist.
