Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612104, here are decompositions:

23 + 31612081 = 31612104
61 + 31612043 = 31612104
107 + 31611997 = 31612104
163 + 31611941 = 31612104
193 + 31611911 = 31612104
197 + 31611907 = 31612104
211 + 31611893 = 31612104
263 + 31611841 = 31612104

Showing the first eight; more decompositions exist.
