Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611948, here are decompositions:

7 + 31611941 = 31611948
31 + 31611917 = 31611948
37 + 31611911 = 31611948
41 + 31611907 = 31611948
79 + 31611869 = 31611948
97 + 31611851 = 31611948
107 + 31611841 = 31611948
131 + 31611817 = 31611948

Showing the first eight; more decompositions exist.
