Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527676, here are decompositions:

17 + 31527659 = 31527676
107 + 31527569 = 31527676
179 + 31527497 = 31527676
263 + 31527413 = 31527676
269 + 31527407 = 31527676
353 + 31527323 = 31527676
359 + 31527317 = 31527676
443 + 31527233 = 31527676

Showing the first eight; more decompositions exist.
