Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718686, here are decompositions:

13 + 8718673 = 8718686
37 + 8718649 = 8718686
199 + 8718487 = 8718686
337 + 8718349 = 8718686
373 + 8718313 = 8718686
409 + 8718277 = 8718686
439 + 8718247 = 8718686
523 + 8718163 = 8718686

Showing the first eight; more decompositions exist.
