Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680690, here are decompositions:

59 + 8680631 = 8680690
71 + 8680619 = 8680690
89 + 8680601 = 8680690
107 + 8680583 = 8680690
131 + 8680559 = 8680690
251 + 8680439 = 8680690
281 + 8680409 = 8680690
311 + 8680379 = 8680690

Showing the first eight; more decompositions exist.
