Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613376, here are decompositions:

19 + 31613357 = 31613376
43 + 31613333 = 31613376
127 + 31613249 = 31613376
149 + 31613227 = 31613376
233 + 31613143 = 31613376
239 + 31613137 = 31613376
257 + 31613119 = 31613376
269 + 31613107 = 31613376

Showing the first eight; more decompositions exist.
