Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532986, here are decompositions:

5 + 31532981 = 31532986
47 + 31532939 = 31532986
113 + 31532873 = 31532986
293 + 31532693 = 31532986
347 + 31532639 = 31532986
389 + 31532597 = 31532986
479 + 31532507 = 31532986
509 + 31532477 = 31532986

Showing the first eight; more decompositions exist.
