Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617678, here are decompositions:

131 + 8617547 = 8617678
239 + 8617439 = 8617678
281 + 8617397 = 8617678
317 + 8617361 = 8617678
359 + 8617319 = 8617678
401 + 8617277 = 8617678
467 + 8617211 = 8617678
491 + 8617187 = 8617678

Showing the first eight; more decompositions exist.
