Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613382, here are decompositions:

5 + 31613377 = 31613382
41 + 31613341 = 31613382
139 + 31613243 = 31613382
191 + 31613191 = 31613382
211 + 31613171 = 31613382
239 + 31613143 = 31613382
263 + 31613119 = 31613382
401 + 31612981 = 31613382

Showing the first eight; more decompositions exist.
