Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688390, here are decompositions:

37 + 8688353 = 8688390
41 + 8688349 = 8688390
79 + 8688311 = 8688390
103 + 8688287 = 8688390
107 + 8688283 = 8688390
131 + 8688259 = 8688390
181 + 8688209 = 8688390
223 + 8688167 = 8688390

Showing the first eight; more decompositions exist.
