Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576496, here are decompositions:

13 + 31576483 = 31576496
19 + 31576477 = 31576496
37 + 31576459 = 31576496
43 + 31576453 = 31576496
79 + 31576417 = 31576496
229 + 31576267 = 31576496
277 + 31576219 = 31576496
379 + 31576117 = 31576496

Showing the first eight; more decompositions exist.
