Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621416, here are decompositions:

3 + 8621413 = 8621416
5 + 8621411 = 8621416
107 + 8621309 = 8621416
173 + 8621243 = 8621416
179 + 8621237 = 8621416
227 + 8621189 = 8621416
233 + 8621183 = 8621416
263 + 8621153 = 8621416

Showing the first eight; more decompositions exist.
