Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613358, here are decompositions:

17 + 31613341 = 31613358
67 + 31613291 = 31613358
109 + 31613249 = 31613358
131 + 31613227 = 31613358
167 + 31613191 = 31613358
239 + 31613119 = 31613358
241 + 31613117 = 31613358
251 + 31613107 = 31613358

Showing the first eight; more decompositions exist.
