Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472022, here are decompositions:

11 + 31472011 = 31472022
19 + 31472003 = 31472022
31 + 31471991 = 31472022
83 + 31471939 = 31472022
89 + 31471933 = 31472022
139 + 31471883 = 31472022
173 + 31471849 = 31472022
191 + 31471831 = 31472022

Showing the first eight; more decompositions exist.
