Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620446, here are decompositions:

17 + 8620429 = 8620446
53 + 8620393 = 8620446
97 + 8620349 = 8620446
139 + 8620307 = 8620446
157 + 8620289 = 8620446
179 + 8620267 = 8620446
227 + 8620219 = 8620446
229 + 8620217 = 8620446

Showing the first eight; more decompositions exist.
