Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532858, here are decompositions:

109 + 31532749 = 31532858
199 + 31532659 = 31532858
271 + 31532587 = 31532858
277 + 31532581 = 31532858
307 + 31532551 = 31532858
337 + 31532521 = 31532858
421 + 31532437 = 31532858
457 + 31532401 = 31532858

Showing the first eight; more decompositions exist.
