Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608726, here are decompositions:

5 + 31608721 = 31608726
13 + 31608713 = 31608726
29 + 31608697 = 31608726
59 + 31608667 = 31608726
137 + 31608589 = 31608726
139 + 31608587 = 31608726
197 + 31608529 = 31608726
199 + 31608527 = 31608726

Showing the first eight; more decompositions exist.
