Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452456, here are decompositions:

5 + 31452451 = 31452456
37 + 31452419 = 31452456
89 + 31452367 = 31452456
173 + 31452283 = 31452456
223 + 31452233 = 31452456
257 + 31452199 = 31452456
283 + 31452173 = 31452456
359 + 31452097 = 31452456

Showing the first eight; more decompositions exist.
