Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454300, here are decompositions:

37 + 31454263 = 31454300
79 + 31454221 = 31454300
103 + 31454197 = 31454300
109 + 31454191 = 31454300
139 + 31454161 = 31454300
151 + 31454149 = 31454300
223 + 31454077 = 31454300
277 + 31454023 = 31454300

Showing the first eight; more decompositions exist.
