Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104942, here are decompositions:

31 + 104911 = 104942
73 + 104869 = 104942
139 + 104803 = 104942
163 + 104779 = 104942
181 + 104761 = 104942
199 + 104743 = 104942
241 + 104701 = 104942
283 + 104659 = 104942

Showing the first eight; more decompositions exist.
