Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611914, here are decompositions:

3 + 31611911 = 31611914
7 + 31611907 = 31611914
31 + 31611883 = 31611914
73 + 31611841 = 31611914
97 + 31611817 = 31611914
157 + 31611757 = 31611914
181 + 31611733 = 31611914
211 + 31611703 = 31611914

Showing the first eight; more decompositions exist.
