Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517536, here are decompositions:

3 + 31517533 = 31517536
137 + 31517399 = 31517536
263 + 31517273 = 31517536
269 + 31517267 = 31517536
293 + 31517243 = 31517536
509 + 31517027 = 31517536
563 + 31516973 = 31517536
647 + 31516889 = 31517536

Showing the first eight; more decompositions exist.
