Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713216, here are decompositions:

3 + 8713213 = 8713216
23 + 8713193 = 8713216
59 + 8713157 = 8713216
89 + 8713127 = 8713216
107 + 8713109 = 8713216
173 + 8713043 = 8713216
179 + 8713037 = 8713216
353 + 8712863 = 8713216

Showing the first eight; more decompositions exist.
