Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613162, here are decompositions:

19 + 31613143 = 31613162
43 + 31613119 = 31613162
109 + 31613053 = 31613162
181 + 31612981 = 31613162
193 + 31612969 = 31613162
211 + 31612951 = 31613162
223 + 31612939 = 31613162
271 + 31612891 = 31613162

Showing the first eight; more decompositions exist.
