Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621446, here are decompositions:

3 + 8621443 = 8621446
17 + 8621429 = 8621446
107 + 8621339 = 8621446
137 + 8621309 = 8621446
233 + 8621213 = 8621446
257 + 8621189 = 8621446
263 + 8621183 = 8621446
293 + 8621153 = 8621446

Showing the first eight; more decompositions exist.
