Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517716, here are decompositions:

17 + 31517699 = 31517716
137 + 31517579 = 31517716
173 + 31517543 = 31517716
317 + 31517399 = 31517716
443 + 31517273 = 31517716
449 + 31517267 = 31517716
509 + 31517207 = 31517716
653 + 31517063 = 31517716

Showing the first eight; more decompositions exist.
