Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452360, here are decompositions:

19 + 31452341 = 31452360
59 + 31452301 = 31452360
127 + 31452233 = 31452360
151 + 31452209 = 31452360
157 + 31452203 = 31452360
179 + 31452181 = 31452360
223 + 31452137 = 31452360
229 + 31452131 = 31452360

Showing the first eight; more decompositions exist.
