Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559710, here are decompositions:

11 + 31559699 = 31559710
23 + 31559687 = 31559710
29 + 31559681 = 31559710
59 + 31559651 = 31559710
71 + 31559639 = 31559710
137 + 31559573 = 31559710
173 + 31559537 = 31559710
239 + 31559471 = 31559710

Showing the first eight; more decompositions exist.
