Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569534, here are decompositions:

43 + 31569491 = 31569534
53 + 31569481 = 31569534
97 + 31569437 = 31569534
167 + 31569367 = 31569534
197 + 31569337 = 31569534
233 + 31569301 = 31569534
257 + 31569277 = 31569534
277 + 31569257 = 31569534

Showing the first eight; more decompositions exist.
