Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611706, here are decompositions:

3 + 31611703 = 31611706
47 + 31611659 = 31611706
59 + 31611647 = 31611706
89 + 31611617 = 31611706
167 + 31611539 = 31611706
179 + 31611527 = 31611706
197 + 31611509 = 31611706
233 + 31611473 = 31611706

Showing the first eight; more decompositions exist.
