Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31022, here are decompositions:

3 + 31019 = 31022
73 + 30949 = 31022
151 + 30871 = 31022
163 + 30859 = 31022
181 + 30841 = 31022
193 + 30829 = 31022
241 + 30781 = 31022
373 + 30649 = 31022

Showing the first eight; more decompositions exist.
