Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123944, here are decompositions:

3 + 123941 = 123944
13 + 123931 = 123944
127 + 123817 = 123944
157 + 123787 = 123944
211 + 123733 = 123944
277 + 123667 = 123944
283 + 123661 = 123944
307 + 123637 = 123944

Showing the first eight; more decompositions exist.
