Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520496, here are decompositions:

5 + 31520491 = 31520496
13 + 31520483 = 31520496
17 + 31520479 = 31520496
43 + 31520453 = 31520496
79 + 31520417 = 31520496
89 + 31520407 = 31520496
97 + 31520399 = 31520496
103 + 31520393 = 31520496

Showing the first eight; more decompositions exist.
