Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565706, here are decompositions:

5 + 31565701 = 31565706
13 + 31565693 = 31565706
43 + 31565663 = 31565706
103 + 31565603 = 31565706
167 + 31565539 = 31565706
233 + 31565473 = 31565706
269 + 31565437 = 31565706
283 + 31565423 = 31565706

Showing the first eight; more decompositions exist.
