Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31312, here are decompositions:

5 + 31307 = 31312
41 + 31271 = 31312
53 + 31259 = 31312
59 + 31253 = 31312
89 + 31223 = 31312
131 + 31181 = 31312
173 + 31139 = 31312
191 + 31121 = 31312

Showing the first eight; more decompositions exist.
