Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476866, here are decompositions:

13 + 31476853 = 31476866
19 + 31476847 = 31476866
37 + 31476829 = 31476866
67 + 31476799 = 31476866
139 + 31476727 = 31476866
163 + 31476703 = 31476866
349 + 31476517 = 31476866
367 + 31476499 = 31476866

Showing the first eight; more decompositions exist.
