Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517710, here are decompositions:

11 + 31517699 = 31517710
71 + 31517639 = 31517710
113 + 31517597 = 31517710
131 + 31517579 = 31517710
137 + 31517573 = 31517710
167 + 31517543 = 31517710
269 + 31517441 = 31517710
293 + 31517417 = 31517710

Showing the first eight; more decompositions exist.
