Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613344, here are decompositions:

3 + 31613341 = 31613344
11 + 31613333 = 31613344
53 + 31613291 = 31613344
101 + 31613243 = 31613344
173 + 31613171 = 31613344
227 + 31613117 = 31613344
317 + 31613027 = 31613344
353 + 31612991 = 31613344

Showing the first eight; more decompositions exist.
