Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622536, here are decompositions:

17 + 31622519 = 31622536
107 + 31622429 = 31622536
167 + 31622369 = 31622536
263 + 31622273 = 31622536
347 + 31622189 = 31622536
353 + 31622183 = 31622536
383 + 31622153 = 31622536
389 + 31622147 = 31622536

Showing the first eight; more decompositions exist.
