Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611676, here are decompositions:

3 + 31611673 = 31611676
17 + 31611659 = 31611676
29 + 31611647 = 31611676
59 + 31611617 = 31611676
137 + 31611539 = 31611676
149 + 31611527 = 31611676
167 + 31611509 = 31611676
347 + 31611329 = 31611676

Showing the first eight; more decompositions exist.
