Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622874, here are decompositions:

11 + 31622863 = 31622874
37 + 31622837 = 31622874
71 + 31622803 = 31622874
97 + 31622777 = 31622874
131 + 31622743 = 31622874
181 + 31622693 = 31622874
191 + 31622683 = 31622874
211 + 31622663 = 31622874

Showing the first eight; more decompositions exist.
