Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567948, here are decompositions:

17 + 31567931 = 31567948
89 + 31567859 = 31567948
179 + 31567769 = 31567948
239 + 31567709 = 31567948
311 + 31567637 = 31567948
389 + 31567559 = 31567948
521 + 31567427 = 31567948
677 + 31567271 = 31567948

Showing the first eight; more decompositions exist.
