Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625822, here are decompositions:

11 + 8625811 = 8625822
13 + 8625809 = 8625822
89 + 8625733 = 8625822
113 + 8625709 = 8625822
173 + 8625649 = 8625822
181 + 8625641 = 8625822
223 + 8625599 = 8625822
263 + 8625559 = 8625822

Showing the first eight; more decompositions exist.
