Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101966, here are decompositions:

3 + 101963 = 101966
37 + 101929 = 101966
97 + 101869 = 101966
103 + 101863 = 101966
127 + 101839 = 101966
229 + 101737 = 101966
313 + 101653 = 101966
367 + 101599 = 101966

Showing the first eight; more decompositions exist.
