Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620356, here are decompositions:

7 + 8620349 = 8620356
29 + 8620327 = 8620356
67 + 8620289 = 8620356
79 + 8620277 = 8620356
89 + 8620267 = 8620356
97 + 8620259 = 8620356
137 + 8620219 = 8620356
139 + 8620217 = 8620356

Showing the first eight; more decompositions exist.
