Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721602, here are decompositions:

3 + 8721599 = 8721602
61 + 8721541 = 8721602
103 + 8721499 = 8721602
199 + 8721403 = 8721602
223 + 8721379 = 8721602
349 + 8721253 = 8721602
523 + 8721079 = 8721602
541 + 8721061 = 8721602

Showing the first eight; more decompositions exist.
