Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611716, here are decompositions:

7 + 31611709 = 31611716
13 + 31611703 = 31611716
43 + 31611673 = 31611716
109 + 31611607 = 31611716
139 + 31611577 = 31611716
163 + 31611553 = 31611716
229 + 31611487 = 31611716
277 + 31611439 = 31611716

Showing the first eight; more decompositions exist.
