Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2944, here are decompositions:

5 + 2939 = 2944
17 + 2927 = 2944
41 + 2903 = 2944
47 + 2897 = 2944
83 + 2861 = 2944
101 + 2843 = 2944
107 + 2837 = 2944
167 + 2777 = 2944

Showing the first eight; more decompositions exist.
