Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721276, here are decompositions:

7 + 8721269 = 8721276
17 + 8721259 = 8721276
23 + 8721253 = 8721276
37 + 8721239 = 8721276
79 + 8721197 = 8721276
197 + 8721079 = 8721276
199 + 8721077 = 8721276
227 + 8721049 = 8721276

Showing the first eight; more decompositions exist.
