Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454304, here are decompositions:

41 + 31454263 = 31454304
83 + 31454221 = 31454304
103 + 31454201 = 31454304
107 + 31454197 = 31454304
113 + 31454191 = 31454304
157 + 31454147 = 31454304
181 + 31454123 = 31454304
223 + 31454081 = 31454304

Showing the first eight; more decompositions exist.
