Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721314, here are decompositions:

3 + 8721311 = 8721314
61 + 8721253 = 8721314
157 + 8721157 = 8721314
193 + 8721121 = 8721314
271 + 8721043 = 8721314
337 + 8720977 = 8721314
367 + 8720947 = 8721314
373 + 8720941 = 8721314

Showing the first eight; more decompositions exist.
