Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454360, here are decompositions:

97 + 31454263 = 31454360
139 + 31454221 = 31454360
163 + 31454197 = 31454360
199 + 31454161 = 31454360
211 + 31454149 = 31454360
277 + 31454083 = 31454360
283 + 31454077 = 31454360
307 + 31454053 = 31454360

Showing the first eight; more decompositions exist.
