Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613354, here are decompositions:

13 + 31613341 = 31613354
127 + 31613227 = 31613354
163 + 31613191 = 31613354
211 + 31613143 = 31613354
373 + 31612981 = 31613354
463 + 31612891 = 31613354
523 + 31612831 = 31613354
601 + 31612753 = 31613354

Showing the first eight; more decompositions exist.
