Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715982, here are decompositions:

5 + 8715977 = 8715982
101 + 8715881 = 8715982
251 + 8715731 = 8715982
263 + 8715719 = 8715982
311 + 8715671 = 8715982
599 + 8715383 = 8715982
659 + 8715323 = 8715982
719 + 8715263 = 8715982

Showing the first eight; more decompositions exist.
