Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562584, here are decompositions:

17 + 31562567 = 31562584
41 + 31562543 = 31562584
83 + 31562501 = 31562584
101 + 31562483 = 31562584
227 + 31562357 = 31562584
293 + 31562291 = 31562584
311 + 31562273 = 31562584
353 + 31562231 = 31562584

Showing the first eight; more decompositions exist.
