Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625906, here are decompositions:

5 + 8625901 = 8625906
17 + 8625889 = 8625906
53 + 8625853 = 8625906
73 + 8625833 = 8625906
97 + 8625809 = 8625906
173 + 8625733 = 8625906
197 + 8625709 = 8625906
199 + 8625707 = 8625906

Showing the first eight; more decompositions exist.
