Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622946, here are decompositions:

7 + 31622939 = 31622946
13 + 31622933 = 31622946
23 + 31622923 = 31622946
53 + 31622893 = 31622946
83 + 31622863 = 31622946
109 + 31622837 = 31622946
137 + 31622809 = 31622946
167 + 31622779 = 31622946

Showing the first eight; more decompositions exist.
