Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566502, here are decompositions:

5 + 31566497 = 31566502
29 + 31566473 = 31566502
53 + 31566449 = 31566502
59 + 31566443 = 31566502
113 + 31566389 = 31566502
173 + 31566329 = 31566502
251 + 31566251 = 31566502
281 + 31566221 = 31566502

Showing the first eight; more decompositions exist.
