Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625972, here are decompositions:

11 + 8625961 = 8625972
13 + 8625959 = 8625972
59 + 8625913 = 8625972
71 + 8625901 = 8625972
83 + 8625889 = 8625972
139 + 8625833 = 8625972
151 + 8625821 = 8625972
163 + 8625809 = 8625972

Showing the first eight; more decompositions exist.
