Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485134, here are decompositions:

13 + 31485121 = 31485134
67 + 31485067 = 31485134
103 + 31485031 = 31485134
193 + 31484941 = 31485134
223 + 31484911 = 31485134
271 + 31484863 = 31485134
313 + 31484821 = 31485134
337 + 31484797 = 31485134

Showing the first eight; more decompositions exist.
