Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496540, here are decompositions:

3 + 31496537 = 31496540
151 + 31496389 = 31496540
211 + 31496329 = 31496540
223 + 31496317 = 31496540
277 + 31496263 = 31496540
331 + 31496209 = 31496540
367 + 31496173 = 31496540
379 + 31496161 = 31496540

Showing the first eight; more decompositions exist.
