Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622932, here are decompositions:

191 + 31622741 = 31622932
233 + 31622699 = 31622932
239 + 31622693 = 31622932
269 + 31622663 = 31622932
353 + 31622579 = 31622932
503 + 31622429 = 31622932
563 + 31622369 = 31622932
659 + 31622273 = 31622932

Showing the first eight; more decompositions exist.
