Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626646, here are decompositions:

3 + 8626643 = 8626646
43 + 8626603 = 8626646
97 + 8626549 = 8626646
139 + 8626507 = 8626646
229 + 8626417 = 8626646
349 + 8626297 = 8626646
397 + 8626249 = 8626646
409 + 8626237 = 8626646

Showing the first eight; more decompositions exist.
