Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701816, here are decompositions:

3 + 8701813 = 8701816
5 + 8701811 = 8701816
59 + 8701757 = 8701816
107 + 8701709 = 8701816
113 + 8701703 = 8701816
173 + 8701643 = 8701816
239 + 8701577 = 8701816
257 + 8701559 = 8701816

Showing the first eight; more decompositions exist.
