Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931942, here are decompositions:

29 + 931913 = 931942
41 + 931901 = 931942
59 + 931883 = 931942
83 + 931859 = 931942
131 + 931811 = 931942
191 + 931751 = 931942
233 + 931709 = 931942
251 + 931691 = 931942

Showing the first eight; more decompositions exist.
