Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31174, here are decompositions:

23 + 31151 = 31174
53 + 31121 = 31174
83 + 31091 = 31174
191 + 30983 = 31174
197 + 30977 = 31174
233 + 30941 = 31174
263 + 30911 = 31174
281 + 30893 = 31174

Showing the first eight; more decompositions exist.
