Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588936, here are decompositions:

3 + 31588933 = 31588936
89 + 31588847 = 31588936
227 + 31588709 = 31588936
257 + 31588679 = 31588936
263 + 31588673 = 31588936
293 + 31588643 = 31588936
443 + 31588493 = 31588936
569 + 31588367 = 31588936

Showing the first eight; more decompositions exist.
