Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721274, here are decompositions:

5 + 8721269 = 8721274
83 + 8721191 = 8721274
173 + 8721101 = 8721274
197 + 8721077 = 8721274
383 + 8720891 = 8721274
467 + 8720807 = 8721274
491 + 8720783 = 8721274
503 + 8720771 = 8721274

Showing the first eight; more decompositions exist.
