Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688272, here are decompositions:

13 + 8688259 = 8688272
139 + 8688133 = 8688272
163 + 8688109 = 8688272
349 + 8687923 = 8688272
601 + 8687671 = 8688272
613 + 8687659 = 8688272
631 + 8687641 = 8688272
673 + 8687599 = 8688272

Showing the first eight; more decompositions exist.
