Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517348, here are decompositions:

151 + 31517197 = 31517348
199 + 31517149 = 31517348
337 + 31517011 = 31517348
367 + 31516981 = 31517348
397 + 31516951 = 31517348
571 + 31516777 = 31517348
619 + 31516729 = 31517348
829 + 31516519 = 31517348

Showing the first eight; more decompositions exist.
