Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476016, here are decompositions:

3 + 31476013 = 31476016
53 + 31475963 = 31476016
107 + 31475909 = 31476016
167 + 31475849 = 31476016
239 + 31475777 = 31476016
347 + 31475669 = 31476016
419 + 31475597 = 31476016
557 + 31475459 = 31476016

Showing the first eight; more decompositions exist.
