Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701810, here are decompositions:

53 + 8701757 = 8701810
101 + 8701709 = 8701810
107 + 8701703 = 8701810
167 + 8701643 = 8701810
179 + 8701631 = 8701810
233 + 8701577 = 8701810
239 + 8701571 = 8701810
251 + 8701559 = 8701810

Showing the first eight; more decompositions exist.
