Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2894, here are decompositions:

7 + 2887 = 2894
37 + 2857 = 2894
43 + 2851 = 2894
61 + 2833 = 2894
97 + 2797 = 2894
103 + 2791 = 2894
127 + 2767 = 2894
163 + 2731 = 2894

Showing the first eight; more decompositions exist.
