Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940646, here are decompositions:

73 + 940573 = 940646
97 + 940549 = 940646
103 + 940543 = 940646
163 + 940483 = 940646
277 + 940369 = 940646
349 + 940297 = 940646
367 + 940279 = 940646
397 + 940249 = 940646

Showing the first eight; more decompositions exist.
