Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517510, here are decompositions:

19 + 31517491 = 31517510
43 + 31517467 = 31517510
97 + 31517413 = 31517510
103 + 31517407 = 31517510
313 + 31517197 = 31517510
499 + 31517011 = 31517510
631 + 31516879 = 31517510
691 + 31516819 = 31517510

Showing the first eight; more decompositions exist.
