Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622892, here are decompositions:

11 + 31622881 = 31622892
29 + 31622863 = 31622892
83 + 31622809 = 31622892
89 + 31622803 = 31622892
113 + 31622779 = 31622892
149 + 31622743 = 31622892
151 + 31622741 = 31622892
163 + 31622729 = 31622892

Showing the first eight; more decompositions exist.
