Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713690, here are decompositions:

47 + 8713643 = 8713690
59 + 8713631 = 8713690
107 + 8713583 = 8713690
113 + 8713577 = 8713690
137 + 8713553 = 8713690
239 + 8713451 = 8713690
257 + 8713433 = 8713690
269 + 8713421 = 8713690

Showing the first eight; more decompositions exist.
