Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718662, here are decompositions:

13 + 8718649 = 8718662
61 + 8718601 = 8718662
193 + 8718469 = 8718662
223 + 8718439 = 8718662
313 + 8718349 = 8718662
349 + 8718313 = 8718662
499 + 8718163 = 8718662
571 + 8718091 = 8718662

Showing the first eight; more decompositions exist.
