Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620456, here are decompositions:

107 + 8620349 = 8620456
149 + 8620307 = 8620456
167 + 8620289 = 8620456
179 + 8620277 = 8620456
197 + 8620259 = 8620456
239 + 8620217 = 8620456
269 + 8620187 = 8620456
347 + 8620109 = 8620456

Showing the first eight; more decompositions exist.
