Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680636, here are decompositions:

5 + 8680631 = 8680636
17 + 8680619 = 8680636
23 + 8680613 = 8680636
53 + 8680583 = 8680636
197 + 8680439 = 8680636
227 + 8680409 = 8680636
257 + 8680379 = 8680636
359 + 8680277 = 8680636

Showing the first eight; more decompositions exist.
