Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713870, here are decompositions:

3 + 8713867 = 8713870
47 + 8713823 = 8713870
59 + 8713811 = 8713870
89 + 8713781 = 8713870
107 + 8713763 = 8713870
149 + 8713721 = 8713870
227 + 8713643 = 8713870
239 + 8713631 = 8713870

Showing the first eight; more decompositions exist.
