Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496616, here are decompositions:

5 + 31496611 = 31496616
17 + 31496599 = 31496616
23 + 31496593 = 31496616
29 + 31496587 = 31496616
43 + 31496573 = 31496616
79 + 31496537 = 31496616
97 + 31496519 = 31496616
127 + 31496489 = 31496616

Showing the first eight; more decompositions exist.
