Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613322, here are decompositions:

31 + 31613291 = 31613322
73 + 31613249 = 31613322
79 + 31613243 = 31613322
131 + 31613191 = 31613322
151 + 31613171 = 31613322
179 + 31613143 = 31613322
269 + 31613053 = 31613322
331 + 31612991 = 31613322

Showing the first eight; more decompositions exist.
