Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566508, here are decompositions:

11 + 31566497 = 31566508
59 + 31566449 = 31566508
131 + 31566377 = 31566508
179 + 31566329 = 31566508
191 + 31566317 = 31566508
257 + 31566251 = 31566508
317 + 31566191 = 31566508
431 + 31566077 = 31566508

Showing the first eight; more decompositions exist.
