Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606922, here are decompositions:

3 + 31606919 = 31606922
19 + 31606903 = 31606922
43 + 31606879 = 31606922
181 + 31606741 = 31606922
211 + 31606711 = 31606922
241 + 31606681 = 31606922
271 + 31606651 = 31606922
379 + 31606543 = 31606922

Showing the first eight; more decompositions exist.
