Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613560, here are decompositions:

47 + 31613513 = 31613560
149 + 31613411 = 31613560
227 + 31613333 = 31613560
269 + 31613291 = 31613560
311 + 31613249 = 31613560
317 + 31613243 = 31613560
389 + 31613171 = 31613560
443 + 31613117 = 31613560

Showing the first eight; more decompositions exist.
