Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458262, here are decompositions:

23 + 31458239 = 31458262
71 + 31458191 = 31458262
89 + 31458173 = 31458262
131 + 31458131 = 31458262
149 + 31458113 = 31458262
179 + 31458083 = 31458262
263 + 31457999 = 31458262
293 + 31457969 = 31458262

Showing the first eight; more decompositions exist.
