Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458354, here are decompositions:

23 + 31458331 = 31458354
43 + 31458311 = 31458354
157 + 31458197 = 31458354
163 + 31458191 = 31458354
167 + 31458187 = 31458354
181 + 31458173 = 31458354
223 + 31458131 = 31458354
241 + 31458113 = 31458354

Showing the first eight; more decompositions exist.
