Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517896, here are decompositions:

17 + 31517879 = 31517896
167 + 31517729 = 31517896
173 + 31517723 = 31517896
197 + 31517699 = 31517896
257 + 31517639 = 31517896
317 + 31517579 = 31517896
353 + 31517543 = 31517896
479 + 31517417 = 31517896

Showing the first eight; more decompositions exist.
