Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712170, here are decompositions:

3 + 8712167 = 8712170
7 + 8712163 = 8712170
13 + 8712157 = 8712170
37 + 8712133 = 8712170
79 + 8712091 = 8712170
151 + 8712019 = 8712170
199 + 8711971 = 8712170
283 + 8711887 = 8712170

Showing the first eight; more decompositions exist.
