Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66942, here are decompositions:

11 + 66931 = 66942
19 + 66923 = 66942
23 + 66919 = 66942
53 + 66889 = 66942
59 + 66883 = 66942
79 + 66863 = 66942
89 + 66853 = 66942
101 + 66841 = 66942

Showing the first eight; more decompositions exist.
