Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458426, here are decompositions:

7 + 31458419 = 31458426
23 + 31458403 = 31458426
47 + 31458379 = 31458426
53 + 31458373 = 31458426
127 + 31458299 = 31458426
149 + 31458277 = 31458426
229 + 31458197 = 31458426
239 + 31458187 = 31458426

Showing the first eight; more decompositions exist.
