Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12944, here are decompositions:

3 + 12941 = 12944
37 + 12907 = 12944
103 + 12841 = 12944
163 + 12781 = 12944
181 + 12763 = 12944
223 + 12721 = 12944
241 + 12703 = 12944
307 + 12637 = 12944

Showing the first eight; more decompositions exist.
