Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606064, here are decompositions:

3 + 31606061 = 31606064
13 + 31606051 = 31606064
151 + 31605913 = 31606064
241 + 31605823 = 31606064
283 + 31605781 = 31606064
307 + 31605757 = 31606064
337 + 31605727 = 31606064
367 + 31605697 = 31606064

Showing the first eight; more decompositions exist.
