Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607836, here are decompositions:

5 + 31607831 = 31607836
47 + 31607789 = 31607836
53 + 31607783 = 31607836
89 + 31607747 = 31607836
149 + 31607687 = 31607836
257 + 31607579 = 31607836
347 + 31607489 = 31607836
389 + 31607447 = 31607836

Showing the first eight; more decompositions exist.
