Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475022, here are decompositions:

13 + 31475009 = 31475022
23 + 31474999 = 31475022
41 + 31474981 = 31475022
53 + 31474969 = 31475022
149 + 31474873 = 31475022
193 + 31474829 = 31475022
239 + 31474783 = 31475022
331 + 31474691 = 31475022

Showing the first eight; more decompositions exist.
