Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562022, here are decompositions:

5 + 31562017 = 31562022
13 + 31562009 = 31562022
29 + 31561993 = 31562022
53 + 31561969 = 31562022
83 + 31561939 = 31562022
103 + 31561919 = 31562022
199 + 31561823 = 31562022
211 + 31561811 = 31562022

Showing the first eight; more decompositions exist.
