Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12942, here are decompositions:

19 + 12923 = 12942
23 + 12919 = 12942
31 + 12911 = 12942
43 + 12899 = 12942
53 + 12889 = 12942
89 + 12853 = 12942
101 + 12841 = 12942
113 + 12829 = 12942

Showing the first eight; more decompositions exist.
