Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517694, here are decompositions:

41 + 31517653 = 31517694
53 + 31517641 = 31517694
97 + 31517597 = 31517694
107 + 31517587 = 31517694
137 + 31517557 = 31517694
151 + 31517543 = 31517694
167 + 31517527 = 31517694
193 + 31517501 = 31517694

Showing the first eight; more decompositions exist.
