Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613310, here are decompositions:

19 + 31613291 = 31613310
61 + 31613249 = 31613310
67 + 31613243 = 31613310
83 + 31613227 = 31613310
139 + 31613171 = 31613310
167 + 31613143 = 31613310
173 + 31613137 = 31613310
191 + 31613119 = 31613310

Showing the first eight; more decompositions exist.
