Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7942, here are decompositions:

5 + 7937 = 7942
23 + 7919 = 7942
41 + 7901 = 7942
59 + 7883 = 7942
89 + 7853 = 7942
101 + 7841 = 7942
113 + 7829 = 7942
149 + 7793 = 7942

Showing the first eight; more decompositions exist.
