Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103942, here are decompositions:

23 + 103919 = 103942
29 + 103913 = 103942
53 + 103889 = 103942
101 + 103841 = 103942
131 + 103811 = 103942
173 + 103769 = 103942
239 + 103703 = 103942
359 + 103583 = 103942

Showing the first eight; more decompositions exist.
