Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66944, here are decompositions:

13 + 66931 = 66944
61 + 66883 = 66944
67 + 66877 = 66944
103 + 66841 = 66944
181 + 66763 = 66944
193 + 66751 = 66944
211 + 66733 = 66944
223 + 66721 = 66944

Showing the first eight; more decompositions exist.
