Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996646, here are decompositions:

17 + 996629 = 996646
29 + 996617 = 996646
47 + 996599 = 996646
83 + 996563 = 996646
107 + 996539 = 996646
239 + 996407 = 996646
317 + 996329 = 996646
353 + 996293 = 996646

Showing the first eight; more decompositions exist.
