Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 896, here are decompositions:

13 + 883 = 896
19 + 877 = 896
37 + 859 = 896
43 + 853 = 896
67 + 829 = 896
73 + 823 = 896
109 + 787 = 896
127 + 769 = 896

Showing the first eight; more decompositions exist.
