Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517926, here are decompositions:

17 + 31517909 = 31517926
47 + 31517879 = 31517926
197 + 31517729 = 31517926
227 + 31517699 = 31517926
347 + 31517579 = 31517926
353 + 31517573 = 31517926
383 + 31517543 = 31517926
509 + 31517417 = 31517926

Showing the first eight; more decompositions exist.
