Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496296, here are decompositions:

3 + 31496293 = 31496296
173 + 31496123 = 31496296
197 + 31496099 = 31496296
239 + 31496057 = 31496296
269 + 31496027 = 31496296
317 + 31495979 = 31496296
347 + 31495949 = 31496296
449 + 31495847 = 31496296

Showing the first eight; more decompositions exist.
