Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476164, here are decompositions:

7 + 31476157 = 31476164
67 + 31476097 = 31476164
151 + 31476013 = 31476164
211 + 31475953 = 31476164
337 + 31475827 = 31476164
367 + 31475797 = 31476164
487 + 31475677 = 31476164
541 + 31475623 = 31476164

Showing the first eight; more decompositions exist.
