Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 892, here are decompositions:

5 + 887 = 892
11 + 881 = 892
29 + 863 = 892
53 + 839 = 892
71 + 821 = 892
83 + 809 = 892
131 + 761 = 892
149 + 743 = 892

Showing the first eight; more decompositions exist.
