Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31318, here are decompositions:

11 + 31307 = 31318
41 + 31277 = 31318
47 + 31271 = 31318
59 + 31259 = 31318
71 + 31247 = 31318
137 + 31181 = 31318
167 + 31151 = 31318
179 + 31139 = 31318

Showing the first eight; more decompositions exist.
