Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940818, here are decompositions:

5 + 940813 = 940818
17 + 940801 = 940818
31 + 940787 = 940818
37 + 940781 = 940818
59 + 940759 = 940818
79 + 940739 = 940818
97 + 940721 = 940818
127 + 940691 = 940818

Showing the first eight; more decompositions exist.
