Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713780, here are decompositions:

17 + 8713763 = 8713780
59 + 8713721 = 8713780
71 + 8713709 = 8713780
137 + 8713643 = 8713780
149 + 8713631 = 8713780
197 + 8713583 = 8713780
227 + 8713553 = 8713780
233 + 8713547 = 8713780

Showing the first eight; more decompositions exist.
