Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496496, here are decompositions:

7 + 31496489 = 31496496
47 + 31496449 = 31496496
67 + 31496429 = 31496496
79 + 31496417 = 31496496
107 + 31496389 = 31496496
127 + 31496369 = 31496496
167 + 31496329 = 31496496
179 + 31496317 = 31496496

Showing the first eight; more decompositions exist.
