Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532898, here are decompositions:

17 + 31532881 = 31532898
31 + 31532867 = 31532898
149 + 31532749 = 31532898
211 + 31532687 = 31532898
239 + 31532659 = 31532898
311 + 31532587 = 31532898
317 + 31532581 = 31532898
347 + 31532551 = 31532898

Showing the first eight; more decompositions exist.
