Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517934, here are decompositions:

23 + 31517911 = 31517934
47 + 31517887 = 31517934
73 + 31517861 = 31517934
83 + 31517851 = 31517934
211 + 31517723 = 31517934
233 + 31517701 = 31517934
281 + 31517653 = 31517934
293 + 31517641 = 31517934

Showing the first eight; more decompositions exist.
