Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458324, here are decompositions:

13 + 31458311 = 31458324
47 + 31458277 = 31458324
127 + 31458197 = 31458324
137 + 31458187 = 31458324
151 + 31458173 = 31458324
193 + 31458131 = 31458324
211 + 31458113 = 31458324
241 + 31458083 = 31458324

Showing the first eight; more decompositions exist.
