Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622326, here are decompositions:

53 + 31622273 = 31622326
89 + 31622237 = 31622326
137 + 31622189 = 31622326
173 + 31622153 = 31622326
179 + 31622147 = 31622326
347 + 31621979 = 31622326
479 + 31621847 = 31622326
587 + 31621739 = 31622326

Showing the first eight; more decompositions exist.
