Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517704, here are decompositions:

3 + 31517701 = 31517704
5 + 31517699 = 31517704
107 + 31517597 = 31517704
131 + 31517573 = 31517704
263 + 31517441 = 31517704
293 + 31517411 = 31517704
311 + 31517393 = 31517704
431 + 31517273 = 31517704

Showing the first eight; more decompositions exist.
