Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613340, here are decompositions:

7 + 31613333 = 31613340
97 + 31613243 = 31613340
113 + 31613227 = 31613340
149 + 31613191 = 31613340
197 + 31613143 = 31613340
223 + 31613117 = 31613340
233 + 31613107 = 31613340
313 + 31613027 = 31613340

Showing the first eight; more decompositions exist.
