Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611896, here are decompositions:

3 + 31611893 = 31611896
13 + 31611883 = 31611896
67 + 31611829 = 31611896
79 + 31611817 = 31611896
139 + 31611757 = 31611896
163 + 31611733 = 31611896
193 + 31611703 = 31611896
223 + 31611673 = 31611896

Showing the first eight; more decompositions exist.
