Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 922, here are decompositions:

3 + 919 = 922
11 + 911 = 922
41 + 881 = 922
59 + 863 = 922
83 + 839 = 922
101 + 821 = 922
113 + 809 = 922
149 + 773 = 922

Showing the first eight; more decompositions exist.
