Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680678, here are decompositions:

47 + 8680631 = 8680678
59 + 8680619 = 8680678
197 + 8680481 = 8680678
239 + 8680439 = 8680678
269 + 8680409 = 8680678
401 + 8680277 = 8680678
449 + 8680229 = 8680678
491 + 8680187 = 8680678

Showing the first eight; more decompositions exist.
