Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452468, here are decompositions:

7 + 31452461 = 31452468
17 + 31452451 = 31452468
67 + 31452401 = 31452468
101 + 31452367 = 31452468
127 + 31452341 = 31452468
167 + 31452301 = 31452468
227 + 31452241 = 31452468
269 + 31452199 = 31452468

Showing the first eight; more decompositions exist.
