Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606956, here are decompositions:

5 + 31606951 = 31606956
13 + 31606943 = 31606956
37 + 31606919 = 31606956
53 + 31606903 = 31606956
109 + 31606847 = 31606956
127 + 31606829 = 31606956
229 + 31606727 = 31606956
313 + 31606643 = 31606956

Showing the first eight; more decompositions exist.
