Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458424, here are decompositions:

5 + 31458419 = 31458424
47 + 31458377 = 31458424
113 + 31458311 = 31458424
227 + 31458197 = 31458424
233 + 31458191 = 31458424
251 + 31458173 = 31458424
293 + 31458131 = 31458424
311 + 31458113 = 31458424

Showing the first eight; more decompositions exist.
