Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597564, here are decompositions:

23 + 31597541 = 31597564
71 + 31597493 = 31597564
197 + 31597367 = 31597564
227 + 31597337 = 31597564
281 + 31597283 = 31597564
311 + 31597253 = 31597564
443 + 31597121 = 31597564
521 + 31597043 = 31597564

Showing the first eight; more decompositions exist.
