Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 874, here are decompositions:

11 + 863 = 874
17 + 857 = 874
47 + 827 = 874
53 + 821 = 874
101 + 773 = 874
113 + 761 = 874
131 + 743 = 874
173 + 701 = 874

Showing the first eight; more decompositions exist.
