Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534458, here are decompositions:

17 + 31534441 = 31534458
29 + 31534429 = 31534458
31 + 31534427 = 31534458
47 + 31534411 = 31534458
89 + 31534369 = 31534458
157 + 31534301 = 31534458
211 + 31534247 = 31534458
227 + 31534231 = 31534458

Showing the first eight; more decompositions exist.
