Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726668, here are decompositions:

311 + 8726357 = 8726668
317 + 8726351 = 8726668
617 + 8726051 = 8726668
641 + 8726027 = 8726668
647 + 8726021 = 8726668
677 + 8725991 = 8726668
719 + 8725949 = 8726668
827 + 8725841 = 8726668

Showing the first eight; more decompositions exist.
