Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567962, here are decompositions:

31 + 31567931 = 31567962
79 + 31567883 = 31567962
103 + 31567859 = 31567962
113 + 31567849 = 31567962
149 + 31567813 = 31567962
193 + 31567769 = 31567962
233 + 31567729 = 31567962
263 + 31567699 = 31567962

Showing the first eight; more decompositions exist.
