Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611566, here are decompositions:

13 + 31611553 = 31611566
79 + 31611487 = 31611566
109 + 31611457 = 31611566
127 + 31611439 = 31611566
163 + 31611403 = 31611566
199 + 31611367 = 31611566
379 + 31611187 = 31611566
439 + 31611127 = 31611566

Showing the first eight; more decompositions exist.
