Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518174, here are decompositions:

11 + 31518163 = 31518174
113 + 31518061 = 31518174
137 + 31518037 = 31518174
151 + 31518023 = 31518174
167 + 31518007 = 31518174
173 + 31518001 = 31518174
211 + 31517963 = 31518174
223 + 31517951 = 31518174

Showing the first eight; more decompositions exist.
