Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688372, here are decompositions:

19 + 8688353 = 8688372
23 + 8688349 = 8688372
61 + 8688311 = 8688372
73 + 8688299 = 8688372
89 + 8688283 = 8688372
101 + 8688271 = 8688372
113 + 8688259 = 8688372
151 + 8688221 = 8688372

Showing the first eight; more decompositions exist.
