Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65966, here are decompositions:

3 + 65963 = 65966
37 + 65929 = 65966
67 + 65899 = 65966
127 + 65839 = 65966
139 + 65827 = 65966
157 + 65809 = 65966
337 + 65629 = 65966
349 + 65617 = 65966

Showing the first eight; more decompositions exist.
