Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496372, here are decompositions:

3 + 31496369 = 31496372
43 + 31496329 = 31496372
79 + 31496293 = 31496372
109 + 31496263 = 31496372
151 + 31496221 = 31496372
163 + 31496209 = 31496372
199 + 31496173 = 31496372
211 + 31496161 = 31496372

Showing the first eight; more decompositions exist.
