Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544022, here are decompositions:

11 + 31544011 = 31544022
31 + 31543991 = 31544022
43 + 31543979 = 31544022
61 + 31543961 = 31544022
109 + 31543913 = 31544022
149 + 31543873 = 31544022
151 + 31543871 = 31544022
163 + 31543859 = 31544022

Showing the first eight; more decompositions exist.
