Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940042, here are decompositions:

11 + 940031 = 940042
23 + 940019 = 940042
41 + 940001 = 940042
53 + 939989 = 940042
71 + 939971 = 940042
251 + 939791 = 940042
269 + 939773 = 940042
293 + 939749 = 940042

Showing the first eight; more decompositions exist.
