Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454342, here are decompositions:

79 + 31454263 = 31454342
151 + 31454191 = 31454342
181 + 31454161 = 31454342
193 + 31454149 = 31454342
349 + 31453993 = 31454342
373 + 31453969 = 31454342
433 + 31453909 = 31454342
463 + 31453879 = 31454342

Showing the first eight; more decompositions exist.
