Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721262, here are decompositions:

3 + 8721259 = 8721262
23 + 8721239 = 8721262
71 + 8721191 = 8721262
233 + 8721029 = 8721262
293 + 8720969 = 8721262
443 + 8720819 = 8721262
479 + 8720783 = 8721262
491 + 8720771 = 8721262

Showing the first eight; more decompositions exist.
