Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944, here are decompositions:

3 + 941 = 944
7 + 937 = 944
37 + 907 = 944
61 + 883 = 944
67 + 877 = 944
157 + 787 = 944
193 + 751 = 944
211 + 733 = 944

Showing the first eight; more decompositions exist.
