Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613346, here are decompositions:

5 + 31613341 = 31613346
13 + 31613333 = 31613346
97 + 31613249 = 31613346
103 + 31613243 = 31613346
227 + 31613119 = 31613346
229 + 31613117 = 31613346
239 + 31613107 = 31613346
293 + 31613053 = 31613346

Showing the first eight; more decompositions exist.
