Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611694, here are decompositions:

47 + 31611647 = 31611694
53 + 31611641 = 31611694
113 + 31611581 = 31611694
167 + 31611527 = 31611694
227 + 31611467 = 31611694
353 + 31611341 = 31611694
383 + 31611311 = 31611694
557 + 31611137 = 31611694

Showing the first eight; more decompositions exist.
