Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612008, here are decompositions:

11 + 31611997 = 31612008
67 + 31611941 = 31612008
97 + 31611911 = 31612008
101 + 31611907 = 31612008
139 + 31611869 = 31612008
157 + 31611851 = 31612008
167 + 31611841 = 31612008
179 + 31611829 = 31612008

Showing the first eight; more decompositions exist.
