Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31148, here are decompositions:

67 + 31081 = 31148
79 + 31069 = 31148
97 + 31051 = 31148
109 + 31039 = 31148
199 + 30949 = 31148
211 + 30937 = 31148
277 + 30871 = 31148
307 + 30841 = 31148

Showing the first eight; more decompositions exist.
