Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157164, here are decompositions:

23 + 157141 = 157164
31 + 157133 = 157164
37 + 157127 = 157164
61 + 157103 = 157164
83 + 157081 = 157164
103 + 157061 = 157164
107 + 157057 = 157164
113 + 157051 = 157164

Showing the first eight; more decompositions exist.
