Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31154, here are decompositions:

3 + 31151 = 31154
7 + 31147 = 31154
31 + 31123 = 31154
73 + 31081 = 31154
103 + 31051 = 31154
223 + 30931 = 31154
283 + 30871 = 31154
313 + 30841 = 31154

Showing the first eight; more decompositions exist.
