Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622886, here are decompositions:

5 + 31622881 = 31622886
23 + 31622863 = 31622886
83 + 31622803 = 31622886
107 + 31622779 = 31622886
109 + 31622777 = 31622886
157 + 31622729 = 31622886
173 + 31622713 = 31622886
193 + 31622693 = 31622886

Showing the first eight; more decompositions exist.
