Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517364, here are decompositions:

97 + 31517267 = 31517364
157 + 31517207 = 31517364
167 + 31517197 = 31517364
337 + 31517027 = 31517364
353 + 31517011 = 31517364
383 + 31516981 = 31517364
523 + 31516841 = 31517364
577 + 31516787 = 31517364

Showing the first eight; more decompositions exist.
