Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613814, here are decompositions:

7 + 31613807 = 31613814
13 + 31613801 = 31613814
17 + 31613797 = 31613814
31 + 31613783 = 31613814
97 + 31613717 = 31613814
191 + 31613623 = 31613814
233 + 31613581 = 31613814
263 + 31613551 = 31613814

Showing the first eight; more decompositions exist.
