Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454112, here are decompositions:

29 + 31454083 = 31454112
31 + 31454081 = 31454112
59 + 31454053 = 31454112
89 + 31454023 = 31454112
181 + 31453931 = 31454112
229 + 31453883 = 31454112
233 + 31453879 = 31454112
271 + 31453841 = 31454112

Showing the first eight; more decompositions exist.
