Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625912, here are decompositions:

11 + 8625901 = 8625912
23 + 8625889 = 8625912
59 + 8625853 = 8625912
79 + 8625833 = 8625912
101 + 8625811 = 8625912
103 + 8625809 = 8625912
179 + 8625733 = 8625912
223 + 8625689 = 8625912

Showing the first eight; more decompositions exist.
