Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66938, here are decompositions:

7 + 66931 = 66938
19 + 66919 = 66938
61 + 66877 = 66938
97 + 66841 = 66938
199 + 66739 = 66938
241 + 66697 = 66938
337 + 66601 = 66938
367 + 66571 = 66938

Showing the first eight; more decompositions exist.
