Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606694, here are decompositions:

3 + 31606691 = 31606694
13 + 31606681 = 31606694
37 + 31606657 = 31606694
43 + 31606651 = 31606694
151 + 31606543 = 31606694
157 + 31606537 = 31606694
271 + 31606423 = 31606694
283 + 31606411 = 31606694

Showing the first eight; more decompositions exist.
