Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454268, here are decompositions:

5 + 31454263 = 31454268
19 + 31454249 = 31454268
47 + 31454221 = 31454268
67 + 31454201 = 31454268
71 + 31454197 = 31454268
107 + 31454161 = 31454268
151 + 31454117 = 31454268
191 + 31454077 = 31454268

Showing the first eight; more decompositions exist.
