Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688320, here are decompositions:

37 + 8688283 = 8688320
61 + 8688259 = 8688320
163 + 8688157 = 8688320
211 + 8688109 = 8688320
307 + 8688013 = 8688320
337 + 8687983 = 8688320
367 + 8687953 = 8688320
397 + 8687923 = 8688320

Showing the first eight; more decompositions exist.
