Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721094, here are decompositions:

17 + 8721077 = 8721094
257 + 8720837 = 8721094
311 + 8720783 = 8721094
401 + 8720693 = 8721094
467 + 8720627 = 8721094
563 + 8720531 = 8721094
617 + 8720477 = 8721094
647 + 8720447 = 8721094

Showing the first eight; more decompositions exist.
