Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475016, here are decompositions:

7 + 31475009 = 31475016
17 + 31474999 = 31475016
19 + 31474997 = 31475016
47 + 31474969 = 31475016
149 + 31474867 = 31475016
233 + 31474783 = 31475016
239 + 31474777 = 31475016
269 + 31474747 = 31475016

Showing the first eight; more decompositions exist.
