Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543022, here are decompositions:

3 + 31543019 = 31543022
13 + 31543009 = 31543022
31 + 31542991 = 31543022
73 + 31542949 = 31543022
79 + 31542943 = 31543022
193 + 31542829 = 31543022
211 + 31542811 = 31543022
223 + 31542799 = 31543022

Showing the first eight; more decompositions exist.
