Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103966, here are decompositions:

3 + 103963 = 103966
47 + 103919 = 103966
53 + 103913 = 103966
179 + 103787 = 103966
197 + 103769 = 103966
263 + 103703 = 103966
347 + 103619 = 103966
353 + 103613 = 103966

Showing the first eight; more decompositions exist.
