Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40942, here are decompositions:

3 + 40939 = 40942
59 + 40883 = 40942
89 + 40853 = 40942
101 + 40841 = 40942
113 + 40829 = 40942
179 + 40763 = 40942
191 + 40751 = 40942
233 + 40709 = 40942

Showing the first eight; more decompositions exist.
