Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612720, here are decompositions:

7 + 8612713 = 8612720
13 + 8612707 = 8612720
19 + 8612701 = 8612720
31 + 8612689 = 8612720
37 + 8612683 = 8612720
79 + 8612641 = 8612720
139 + 8612581 = 8612720
223 + 8612497 = 8612720

Showing the first eight; more decompositions exist.
