Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945942, here are decompositions:

5 + 945937 = 945942
13 + 945929 = 945942
43 + 945899 = 945942
59 + 945883 = 945942
61 + 945881 = 945942
131 + 945811 = 945942
211 + 945731 = 945942
241 + 945701 = 945942

Showing the first eight; more decompositions exist.
