Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454252, here are decompositions:

3 + 31454249 = 31454252
31 + 31454221 = 31454252
61 + 31454191 = 31454252
103 + 31454149 = 31454252
199 + 31454053 = 31454252
229 + 31454023 = 31454252
283 + 31453969 = 31454252
373 + 31453879 = 31454252

Showing the first eight; more decompositions exist.
