Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516702, here are decompositions:

3 + 31516699 = 31516702
5 + 31516697 = 31516702
71 + 31516631 = 31516702
83 + 31516619 = 31516702
89 + 31516613 = 31516702
131 + 31516571 = 31516702
179 + 31516523 = 31516702
233 + 31516469 = 31516702

Showing the first eight; more decompositions exist.
