Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588968, here are decompositions:

11 + 31588957 = 31588968
17 + 31588951 = 31588968
41 + 31588927 = 31588968
71 + 31588897 = 31588968
269 + 31588699 = 31588968
311 + 31588657 = 31588968
337 + 31588631 = 31588968
569 + 31588399 = 31588968

Showing the first eight; more decompositions exist.
