Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496568, here are decompositions:

17 + 31496551 = 31496568
29 + 31496539 = 31496568
31 + 31496537 = 31496568
79 + 31496489 = 31496568
127 + 31496441 = 31496568
139 + 31496429 = 31496568
149 + 31496419 = 31496568
151 + 31496417 = 31496568

Showing the first eight; more decompositions exist.
