Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496316, here are decompositions:

23 + 31496293 = 31496316
53 + 31496263 = 31496316
97 + 31496219 = 31496316
107 + 31496209 = 31496316
193 + 31496123 = 31496316
197 + 31496119 = 31496316
233 + 31496083 = 31496316
337 + 31495979 = 31496316

Showing the first eight; more decompositions exist.
