Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943666, here are decompositions:

29 + 943637 = 943666
167 + 943499 = 943666
257 + 943409 = 943666
263 + 943403 = 943666
293 + 943373 = 943666
359 + 943307 = 943666
389 + 943277 = 943666
467 + 943199 = 943666

Showing the first eight; more decompositions exist.
