Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517706, here are decompositions:

5 + 31517701 = 31517706
7 + 31517699 = 31517706
53 + 31517653 = 31517706
67 + 31517639 = 31517706
89 + 31517617 = 31517706
109 + 31517597 = 31517706
127 + 31517579 = 31517706
149 + 31517557 = 31517706

Showing the first eight; more decompositions exist.
