Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461468, here are decompositions:

11 + 31461457 = 31461468
41 + 31461427 = 31461468
107 + 31461361 = 31461468
127 + 31461341 = 31461468
167 + 31461301 = 31461468
239 + 31461229 = 31461468
277 + 31461191 = 31461468
307 + 31461161 = 31461468

Showing the first eight; more decompositions exist.
