Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567926, here are decompositions:

43 + 31567883 = 31567926
67 + 31567859 = 31567926
107 + 31567819 = 31567926
113 + 31567813 = 31567926
157 + 31567769 = 31567926
197 + 31567729 = 31567926
227 + 31567699 = 31567926
233 + 31567693 = 31567926

Showing the first eight; more decompositions exist.
