Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620450, here are decompositions:

89 + 8620361 = 8620450
101 + 8620349 = 8620450
173 + 8620277 = 8620450
191 + 8620259 = 8620450
233 + 8620217 = 8620450
239 + 8620211 = 8620450
263 + 8620187 = 8620450
317 + 8620133 = 8620450

Showing the first eight; more decompositions exist.
