Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559662, here are decompositions:

3 + 31559659 = 31559662
11 + 31559651 = 31559662
23 + 31559639 = 31559662
89 + 31559573 = 31559662
191 + 31559471 = 31559662
311 + 31559351 = 31559662
443 + 31559219 = 31559662
569 + 31559093 = 31559662

Showing the first eight; more decompositions exist.
