Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713666, here are decompositions:

23 + 8713643 = 8713666
83 + 8713583 = 8713666
89 + 8713577 = 8713666
113 + 8713553 = 8713666
179 + 8713487 = 8713666
233 + 8713433 = 8713666
263 + 8713403 = 8713666
293 + 8713373 = 8713666

Showing the first eight; more decompositions exist.
