Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611804, here are decompositions:

43 + 31611761 = 31611804
47 + 31611757 = 31611804
67 + 31611737 = 31611804
71 + 31611733 = 31611804
101 + 31611703 = 31611804
131 + 31611673 = 31611804
137 + 31611667 = 31611804
157 + 31611647 = 31611804

Showing the first eight; more decompositions exist.
