Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468276, here are decompositions:

5 + 31468271 = 31468276
17 + 31468259 = 31468276
29 + 31468247 = 31468276
53 + 31468223 = 31468276
107 + 31468169 = 31468276
179 + 31468097 = 31468276
263 + 31468013 = 31468276
293 + 31467983 = 31468276

Showing the first eight; more decompositions exist.
