Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532998, here are decompositions:

17 + 31532981 = 31532998
59 + 31532939 = 31532998
131 + 31532867 = 31532998
311 + 31532687 = 31532998
359 + 31532639 = 31532998
401 + 31532597 = 31532998
491 + 31532507 = 31532998
509 + 31532489 = 31532998

Showing the first eight; more decompositions exist.
