Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123956, here are decompositions:

3 + 123953 = 123956
103 + 123853 = 123956
127 + 123829 = 123956
139 + 123817 = 123956
199 + 123757 = 123956
223 + 123733 = 123956
229 + 123727 = 123956
337 + 123619 = 123956

Showing the first eight; more decompositions exist.
