Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31132, here are decompositions:

11 + 31121 = 31132
41 + 31091 = 31132
53 + 31079 = 31132
113 + 31019 = 31132
149 + 30983 = 31132
191 + 30941 = 31132
239 + 30893 = 31132
251 + 30881 = 31132

Showing the first eight; more decompositions exist.
