Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83942, here are decompositions:

3 + 83939 = 83942
31 + 83911 = 83942
73 + 83869 = 83942
109 + 83833 = 83942
151 + 83791 = 83942
181 + 83761 = 83942
223 + 83719 = 83942
241 + 83701 = 83942

Showing the first eight; more decompositions exist.
