Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621246, here are decompositions:

3 + 8621243 = 8621246
37 + 8621209 = 8621246
103 + 8621143 = 8621246
157 + 8621089 = 8621246
163 + 8621083 = 8621246
199 + 8621047 = 8621246
229 + 8621017 = 8621246
349 + 8620897 = 8621246

Showing the first eight; more decompositions exist.
