Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612010, here are decompositions:

13 + 31611997 = 31612010
103 + 31611907 = 31612010
127 + 31611883 = 31612010
181 + 31611829 = 31612010
193 + 31611817 = 31612010
277 + 31611733 = 31612010
307 + 31611703 = 31612010
337 + 31611673 = 31612010

Showing the first eight; more decompositions exist.
