Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622126, here are decompositions:

7 + 31622119 = 31622126
13 + 31622113 = 31622126
79 + 31622047 = 31622126
163 + 31621963 = 31622126
229 + 31621897 = 31622126
373 + 31621753 = 31622126
433 + 31621693 = 31622126
457 + 31621669 = 31622126

Showing the first eight; more decompositions exist.
