Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569496, here are decompositions:

5 + 31569491 = 31569496
17 + 31569479 = 31569496
47 + 31569449 = 31569496
59 + 31569437 = 31569496
137 + 31569359 = 31569496
149 + 31569347 = 31569496
239 + 31569257 = 31569496
263 + 31569233 = 31569496

Showing the first eight; more decompositions exist.
