Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517266, here are decompositions:

23 + 31517243 = 31517266
59 + 31517207 = 31517266
227 + 31517039 = 31517266
239 + 31517027 = 31517266
293 + 31516973 = 31517266
479 + 31516787 = 31517266
509 + 31516757 = 31517266
563 + 31516703 = 31517266

Showing the first eight; more decompositions exist.
