Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993646, here are decompositions:

29 + 993617 = 993646
89 + 993557 = 993646
167 + 993479 = 993646
179 + 993467 = 993646
239 + 993407 = 993646
359 + 993287 = 993646
443 + 993203 = 993646
449 + 993197 = 993646

Showing the first eight; more decompositions exist.
