Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680988, here are decompositions:

37 + 8680951 = 8680988
67 + 8680921 = 8680988
79 + 8680909 = 8680988
271 + 8680717 = 8680988
487 + 8680501 = 8680988
571 + 8680417 = 8680988
619 + 8680369 = 8680988
661 + 8680327 = 8680988

Showing the first eight; more decompositions exist.
