Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517746, here are decompositions:

17 + 31517729 = 31517746
23 + 31517723 = 31517746
47 + 31517699 = 31517746
107 + 31517639 = 31517746
149 + 31517597 = 31517746
167 + 31517579 = 31517746
173 + 31517573 = 31517746
347 + 31517399 = 31517746

Showing the first eight; more decompositions exist.
