Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606696, here are decompositions:

5 + 31606691 = 31606696
29 + 31606667 = 31606696
53 + 31606643 = 31606696
113 + 31606583 = 31606696
137 + 31606559 = 31606696
167 + 31606529 = 31606696
179 + 31606517 = 31606696
197 + 31606499 = 31606696

Showing the first eight; more decompositions exist.
