Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940942, here are decompositions:

11 + 940931 = 940942
29 + 940913 = 940942
53 + 940889 = 940942
71 + 940871 = 940942
89 + 940853 = 940942
113 + 940829 = 940942
239 + 940703 = 940942
251 + 940691 = 940942

Showing the first eight; more decompositions exist.
