Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468366, here are decompositions:

29 + 31468337 = 31468366
47 + 31468319 = 31468366
107 + 31468259 = 31468366
197 + 31468169 = 31468366
269 + 31468097 = 31468366
353 + 31468013 = 31468366
383 + 31467983 = 31468366
467 + 31467899 = 31468366

Showing the first eight; more decompositions exist.
