Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452348, here are decompositions:

7 + 31452341 = 31452348
47 + 31452301 = 31452348
107 + 31452241 = 31452348
139 + 31452209 = 31452348
149 + 31452199 = 31452348
167 + 31452181 = 31452348
211 + 31452137 = 31452348
227 + 31452121 = 31452348

Showing the first eight; more decompositions exist.
