Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621536, here are decompositions:

59 + 8621477 = 8621536
83 + 8621453 = 8621536
107 + 8621429 = 8621536
197 + 8621339 = 8621536
227 + 8621309 = 8621536
293 + 8621243 = 8621536
347 + 8621189 = 8621536
353 + 8621183 = 8621536

Showing the first eight; more decompositions exist.
