Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606006, here are decompositions:

23 + 31605983 = 31606006
53 + 31605953 = 31606006
197 + 31605809 = 31606006
227 + 31605779 = 31606006
233 + 31605773 = 31606006
293 + 31605713 = 31606006
317 + 31605689 = 31606006
449 + 31605557 = 31606006

Showing the first eight; more decompositions exist.
