Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517676, here are decompositions:

23 + 31517653 = 31517676
37 + 31517639 = 31517676
59 + 31517617 = 31517676
79 + 31517597 = 31517676
89 + 31517587 = 31517676
97 + 31517579 = 31517676
103 + 31517573 = 31517676
149 + 31517527 = 31517676

Showing the first eight; more decompositions exist.
