Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613552, here are decompositions:

13 + 31613539 = 31613552
151 + 31613401 = 31613552
211 + 31613341 = 31613552
409 + 31613143 = 31613552
433 + 31613119 = 31613552
499 + 31613053 = 31613552
571 + 31612981 = 31613552
601 + 31612951 = 31613552

Showing the first eight; more decompositions exist.
