Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516704, here are decompositions:

5 + 31516699 = 31516704
7 + 31516697 = 31516704
71 + 31516633 = 31516704
73 + 31516631 = 31516704
101 + 31516603 = 31516704
137 + 31516567 = 31516704
181 + 31516523 = 31516704
211 + 31516493 = 31516704

Showing the first eight; more decompositions exist.
