Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599712, here are decompositions:

5 + 31599707 = 31599712
29 + 31599683 = 31599712
41 + 31599671 = 31599712
59 + 31599653 = 31599712
83 + 31599629 = 31599712
101 + 31599611 = 31599712
113 + 31599599 = 31599712
149 + 31599563 = 31599712

Showing the first eight; more decompositions exist.
