Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625090, here are decompositions:

7 + 8625083 = 8625090
13 + 8625077 = 8625090
17 + 8625073 = 8625090
31 + 8625059 = 8625090
37 + 8625053 = 8625090
79 + 8625011 = 8625090
83 + 8625007 = 8625090
109 + 8624981 = 8625090

Showing the first eight; more decompositions exist.
