Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532016, here are decompositions:

13 + 31532003 = 31532016
107 + 31531909 = 31532016
199 + 31531817 = 31532016
337 + 31531679 = 31532016
349 + 31531667 = 31532016
367 + 31531649 = 31532016
389 + 31531627 = 31532016
563 + 31531453 = 31532016

Showing the first eight; more decompositions exist.
