Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613318, here are decompositions:

127 + 31613191 = 31613318
181 + 31613137 = 31613318
199 + 31613119 = 31613318
211 + 31613107 = 31613318
337 + 31612981 = 31613318
349 + 31612969 = 31613318
367 + 31612951 = 31613318
379 + 31612939 = 31613318

Showing the first eight; more decompositions exist.
