Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688370, here are decompositions:

17 + 8688353 = 8688370
59 + 8688311 = 8688370
71 + 8688299 = 8688370
83 + 8688287 = 8688370
149 + 8688221 = 8688370
167 + 8688203 = 8688370
227 + 8688143 = 8688370
269 + 8688101 = 8688370

Showing the first eight; more decompositions exist.
