Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458322, here are decompositions:

11 + 31458311 = 31458322
23 + 31458299 = 31458322
83 + 31458239 = 31458322
131 + 31458191 = 31458322
149 + 31458173 = 31458322
191 + 31458131 = 31458322
239 + 31458083 = 31458322
353 + 31457969 = 31458322

Showing the first eight; more decompositions exist.
