Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621312, here are decompositions:

3 + 8621309 = 8621312
13 + 8621299 = 8621312
31 + 8621281 = 8621312
103 + 8621209 = 8621312
211 + 8621101 = 8621312
223 + 8621089 = 8621312
229 + 8621083 = 8621312
439 + 8620873 = 8621312

Showing the first eight; more decompositions exist.
