Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496266, here are decompositions:

3 + 31496263 = 31496266
5 + 31496261 = 31496266
47 + 31496219 = 31496266
167 + 31496099 = 31496266
239 + 31496027 = 31496266
317 + 31495949 = 31496266
419 + 31495847 = 31496266
509 + 31495757 = 31496266

Showing the first eight; more decompositions exist.
