Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567960, here are decompositions:

29 + 31567931 = 31567960
101 + 31567859 = 31567960
191 + 31567769 = 31567960
251 + 31567709 = 31567960
311 + 31567649 = 31567960
317 + 31567643 = 31567960
401 + 31567559 = 31567960
449 + 31567511 = 31567960

Showing the first eight; more decompositions exist.
