Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31288, here are decompositions:

11 + 31277 = 31288
17 + 31271 = 31288
29 + 31259 = 31288
41 + 31247 = 31288
107 + 31181 = 31288
137 + 31151 = 31288
149 + 31139 = 31288
167 + 31121 = 31288

Showing the first eight; more decompositions exist.
