Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496534, here are decompositions:

163 + 31496371 = 31496534
241 + 31496293 = 31496534
271 + 31496263 = 31496534
313 + 31496221 = 31496534
373 + 31496161 = 31496534
523 + 31496011 = 31496534
613 + 31495921 = 31496534
733 + 31495801 = 31496534

Showing the first eight; more decompositions exist.
