Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622944, here are decompositions:

5 + 31622939 = 31622944
11 + 31622933 = 31622944
107 + 31622837 = 31622944
167 + 31622777 = 31622944
251 + 31622693 = 31622944
257 + 31622687 = 31622944
281 + 31622663 = 31622944
761 + 31622183 = 31622944

Showing the first eight; more decompositions exist.
