Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611474, here are decompositions:

7 + 31611467 = 31611474
17 + 31611457 = 31611474
71 + 31611403 = 31611474
107 + 31611367 = 31611474
151 + 31611323 = 31611474
163 + 31611311 = 31611474
173 + 31611301 = 31611474
311 + 31611163 = 31611474

Showing the first eight; more decompositions exist.
