Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620438, here are decompositions:

89 + 8620349 = 8620438
131 + 8620307 = 8620438
149 + 8620289 = 8620438
179 + 8620259 = 8620438
227 + 8620211 = 8620438
251 + 8620187 = 8620438
317 + 8620121 = 8620438
389 + 8620049 = 8620438

Showing the first eight; more decompositions exist.
