Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680666, here are decompositions:

47 + 8680619 = 8680666
53 + 8680613 = 8680666
83 + 8680583 = 8680666
107 + 8680559 = 8680666
227 + 8680439 = 8680666
257 + 8680409 = 8680666
353 + 8680313 = 8680666
359 + 8680307 = 8680666

Showing the first eight; more decompositions exist.
