Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605606, here are decompositions:

13 + 31605593 = 31605606
23 + 31605583 = 31605606
29 + 31605577 = 31605606
89 + 31605517 = 31605606
163 + 31605443 = 31605606
167 + 31605439 = 31605606
199 + 31605407 = 31605606
229 + 31605377 = 31605606

Showing the first eight; more decompositions exist.
