Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567836, here are decompositions:

17 + 31567819 = 31567836
23 + 31567813 = 31567836
67 + 31567769 = 31567836
107 + 31567729 = 31567836
127 + 31567709 = 31567836
137 + 31567699 = 31567836
149 + 31567687 = 31567836
163 + 31567673 = 31567836

Showing the first eight; more decompositions exist.
