Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605706, here are decompositions:

5 + 31605701 = 31605706
17 + 31605689 = 31605706
113 + 31605593 = 31605706
149 + 31605557 = 31605706
263 + 31605443 = 31605706
443 + 31605263 = 31605706
449 + 31605257 = 31605706
467 + 31605239 = 31605706

Showing the first eight; more decompositions exist.
