Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622956, here are decompositions:

5 + 31622951 = 31622956
17 + 31622939 = 31622956
23 + 31622933 = 31622956
179 + 31622777 = 31622956
227 + 31622729 = 31622956
257 + 31622699 = 31622956
263 + 31622693 = 31622956
269 + 31622687 = 31622956

Showing the first eight; more decompositions exist.
