Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611606, here are decompositions:

23 + 31611583 = 31611606
29 + 31611577 = 31611606
53 + 31611553 = 31611606
67 + 31611539 = 31611606
79 + 31611527 = 31611606
97 + 31611509 = 31611606
139 + 31611467 = 31611606
149 + 31611457 = 31611606

Showing the first eight; more decompositions exist.
