Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566586, here are decompositions:

59 + 31566527 = 31566586
89 + 31566497 = 31566586
113 + 31566473 = 31566586
137 + 31566449 = 31566586
197 + 31566389 = 31566586
239 + 31566347 = 31566586
257 + 31566329 = 31566586
269 + 31566317 = 31566586

Showing the first eight; more decompositions exist.
