Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31112, here are decompositions:

31 + 31081 = 31112
43 + 31069 = 31112
61 + 31051 = 31112
73 + 31039 = 31112
79 + 31033 = 31112
163 + 30949 = 31112
181 + 30931 = 31112
241 + 30871 = 31112

Showing the first eight; more decompositions exist.
