Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622906, here are decompositions:

13 + 31622893 = 31622906
43 + 31622863 = 31622906
97 + 31622809 = 31622906
103 + 31622803 = 31622906
127 + 31622779 = 31622906
163 + 31622743 = 31622906
193 + 31622713 = 31622906
223 + 31622683 = 31622906

Showing the first eight; more decompositions exist.
