Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534534, here are decompositions:

41 + 31534493 = 31534534
47 + 31534487 = 31534534
107 + 31534427 = 31534534
191 + 31534343 = 31534534
233 + 31534301 = 31534534
263 + 31534271 = 31534534
293 + 31534241 = 31534534
347 + 31534187 = 31534534

Showing the first eight; more decompositions exist.
