Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534474, here are decompositions:

17 + 31534457 = 31534474
47 + 31534427 = 31534474
131 + 31534343 = 31534474
173 + 31534301 = 31534474
227 + 31534247 = 31534474
233 + 31534241 = 31534474
353 + 31534121 = 31534474
401 + 31534073 = 31534474

Showing the first eight; more decompositions exist.
