Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 894, here are decompositions:

7 + 887 = 894
11 + 883 = 894
13 + 881 = 894
17 + 877 = 894
31 + 863 = 894
37 + 857 = 894
41 + 853 = 894
67 + 827 = 894

Showing the first eight; more decompositions exist.
