Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496458, here are decompositions:

17 + 31496441 = 31496458
29 + 31496429 = 31496458
41 + 31496417 = 31496458
89 + 31496369 = 31496458
137 + 31496321 = 31496458
197 + 31496261 = 31496458
239 + 31496219 = 31496458
317 + 31496141 = 31496458

Showing the first eight; more decompositions exist.
