Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12956, here are decompositions:

3 + 12953 = 12956
37 + 12919 = 12956
67 + 12889 = 12956
103 + 12853 = 12956
127 + 12829 = 12956
157 + 12799 = 12956
193 + 12763 = 12956
199 + 12757 = 12956

Showing the first eight; more decompositions exist.
