Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721514, here are decompositions:

3 + 8721511 = 8721514
41 + 8721473 = 8721514
47 + 8721467 = 8721514
71 + 8721443 = 8721514
101 + 8721413 = 8721514
233 + 8721281 = 8721514
317 + 8721197 = 8721514
677 + 8720837 = 8721514

Showing the first eight; more decompositions exist.
