Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613422, here are decompositions:

11 + 31613411 = 31613422
23 + 31613399 = 31613422
89 + 31613333 = 31613422
131 + 31613291 = 31613422
173 + 31613249 = 31613422
179 + 31613243 = 31613422
251 + 31613171 = 31613422
431 + 31612991 = 31613422

Showing the first eight; more decompositions exist.
