Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713686, here are decompositions:

43 + 8713643 = 8713686
83 + 8713603 = 8713686
103 + 8713583 = 8713686
109 + 8713577 = 8713686
139 + 8713547 = 8713686
167 + 8713519 = 8713686
173 + 8713513 = 8713686
199 + 8713487 = 8713686

Showing the first eight; more decompositions exist.
