Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496332, here are decompositions:

3 + 31496329 = 31496332
11 + 31496321 = 31496332
71 + 31496261 = 31496332
113 + 31496219 = 31496332
191 + 31496141 = 31496332
233 + 31496099 = 31496332
353 + 31495979 = 31496332
383 + 31495949 = 31496332

Showing the first eight; more decompositions exist.
