Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622974, here are decompositions:

23 + 31622951 = 31622974
41 + 31622933 = 31622974
137 + 31622837 = 31622974
197 + 31622777 = 31622974
233 + 31622741 = 31622974
281 + 31622693 = 31622974
311 + 31622663 = 31622974
701 + 31622273 = 31622974

Showing the first eight; more decompositions exist.
