Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532588, here are decompositions:

7 + 31532581 = 31532588
37 + 31532551 = 31532588
67 + 31532521 = 31532588
151 + 31532437 = 31532588
379 + 31532209 = 31532588
421 + 31532167 = 31532588
499 + 31532089 = 31532588
1009 + 31531579 = 31532588

Showing the first eight; more decompositions exist.
