Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701870, here are decompositions:

17 + 8701853 = 8701870
59 + 8701811 = 8701870
113 + 8701757 = 8701870
167 + 8701703 = 8701870
227 + 8701643 = 8701870
239 + 8701631 = 8701870
293 + 8701577 = 8701870
311 + 8701559 = 8701870

Showing the first eight; more decompositions exist.
