Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564, here are decompositions:

17 + 31547 = 31564
23 + 31541 = 31564
47 + 31517 = 31564
53 + 31511 = 31564
83 + 31481 = 31564
167 + 31397 = 31564
173 + 31391 = 31564
227 + 31337 = 31564

Showing the first eight; more decompositions exist.
