Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611740, here are decompositions:

3 + 31611737 = 31611740
7 + 31611733 = 31611740
31 + 31611709 = 31611740
37 + 31611703 = 31611740
67 + 31611673 = 31611740
73 + 31611667 = 31611740
157 + 31611583 = 31611740
163 + 31611577 = 31611740

Showing the first eight; more decompositions exist.
