Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607700, here are decompositions:

11 + 31607689 = 31607700
13 + 31607687 = 31607700
17 + 31607683 = 31607700
29 + 31607671 = 31607700
71 + 31607629 = 31607700
101 + 31607599 = 31607700
149 + 31607551 = 31607700
197 + 31607503 = 31607700

Showing the first eight; more decompositions exist.
