Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625966, here are decompositions:

5 + 8625961 = 8625966
7 + 8625959 = 8625966
53 + 8625913 = 8625966
113 + 8625853 = 8625966
157 + 8625809 = 8625966
179 + 8625787 = 8625966
233 + 8625733 = 8625966
257 + 8625709 = 8625966

Showing the first eight; more decompositions exist.
