Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453468, here are decompositions:

5 + 31453463 = 31453468
41 + 31453427 = 31453468
47 + 31453421 = 31453468
107 + 31453361 = 31453468
227 + 31453241 = 31453468
311 + 31453157 = 31453468
491 + 31452977 = 31453468
617 + 31452851 = 31453468

Showing the first eight; more decompositions exist.
