Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645246, here are decompositions:

3 + 8645243 = 8645246
7 + 8645239 = 8645246
67 + 8645179 = 8645246
193 + 8645053 = 8645246
199 + 8645047 = 8645246
223 + 8645023 = 8645246
283 + 8644963 = 8645246
373 + 8644873 = 8645246

Showing the first eight; more decompositions exist.
