Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468252, here are decompositions:

5 + 31468247 = 31468252
29 + 31468223 = 31468252
41 + 31468211 = 31468252
83 + 31468169 = 31468252
239 + 31468013 = 31468252
251 + 31468001 = 31468252
269 + 31467983 = 31468252
353 + 31467899 = 31468252

Showing the first eight; more decompositions exist.
