Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713220, here are decompositions:

3 + 8713217 = 8713220
7 + 8713213 = 8713220
79 + 8713141 = 8713220
97 + 8713123 = 8713220
151 + 8713069 = 8713220
211 + 8713009 = 8713220
223 + 8712997 = 8713220
463 + 8712757 = 8713220

Showing the first eight; more decompositions exist.
