Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502022, here are decompositions:

43 + 31501979 = 31502022
109 + 31501913 = 31502022
173 + 31501849 = 31502022
191 + 31501831 = 31502022
199 + 31501823 = 31502022
241 + 31501781 = 31502022
263 + 31501759 = 31502022
271 + 31501751 = 31502022

Showing the first eight; more decompositions exist.
