Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458196, here are decompositions:

5 + 31458191 = 31458196
23 + 31458173 = 31458196
83 + 31458113 = 31458196
113 + 31458083 = 31458196
197 + 31457999 = 31458196
227 + 31457969 = 31458196
293 + 31457903 = 31458196
347 + 31457849 = 31458196

Showing the first eight; more decompositions exist.
