Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625990, here are decompositions:

7 + 8625983 = 8625990
11 + 8625979 = 8625990
17 + 8625973 = 8625990
29 + 8625961 = 8625990
31 + 8625959 = 8625990
89 + 8625901 = 8625990
101 + 8625889 = 8625990
137 + 8625853 = 8625990

Showing the first eight; more decompositions exist.
