Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613412, here are decompositions:

11 + 31613401 = 31613412
13 + 31613399 = 31613412
29 + 31613383 = 31613412
71 + 31613341 = 31613412
79 + 31613333 = 31613412
163 + 31613249 = 31613412
241 + 31613171 = 31613412
269 + 31613143 = 31613412

Showing the first eight; more decompositions exist.
