Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123950, here are decompositions:

19 + 123931 = 123950
97 + 123853 = 123950
163 + 123787 = 123950
193 + 123757 = 123950
223 + 123727 = 123950
283 + 123667 = 123950
313 + 123637 = 123950
331 + 123619 = 123950

Showing the first eight; more decompositions exist.
