Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940810, here are decompositions:

23 + 940787 = 940810
29 + 940781 = 940810
71 + 940739 = 940810
83 + 940727 = 940810
89 + 940721 = 940810
107 + 940703 = 940810
191 + 940619 = 940810
257 + 940553 = 940810

Showing the first eight; more decompositions exist.
