Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688438, here are decompositions:

29 + 8688409 = 8688438
41 + 8688397 = 8688438
89 + 8688349 = 8688438
127 + 8688311 = 8688438
139 + 8688299 = 8688438
151 + 8688287 = 8688438
167 + 8688271 = 8688438
179 + 8688259 = 8688438

Showing the first eight; more decompositions exist.
