Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611634, here are decompositions:

17 + 31611617 = 31611634
53 + 31611581 = 31611634
107 + 31611527 = 31611634
167 + 31611467 = 31611634
293 + 31611341 = 31611634
311 + 31611323 = 31611634
521 + 31611113 = 31611634
617 + 31611017 = 31611634

Showing the first eight; more decompositions exist.
