Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31258, here are decompositions:

5 + 31253 = 31258
11 + 31247 = 31258
107 + 31151 = 31258
137 + 31121 = 31258
167 + 31091 = 31258
179 + 31079 = 31258
239 + 31019 = 31258
281 + 30977 = 31258

Showing the first eight; more decompositions exist.
