Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624130, here are decompositions:

19 + 8624111 = 8624130
29 + 8624101 = 8624130
71 + 8624059 = 8624130
79 + 8624051 = 8624130
103 + 8624027 = 8624130
107 + 8624023 = 8624130
113 + 8624017 = 8624130
127 + 8624003 = 8624130

Showing the first eight; more decompositions exist.
