Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606, here are decompositions:

5 + 31601 = 31606
23 + 31583 = 31606
59 + 31547 = 31606
89 + 31517 = 31606
137 + 31469 = 31606
227 + 31379 = 31606
269 + 31337 = 31606
347 + 31259 = 31606

Showing the first eight; more decompositions exist.
