Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458316, here are decompositions:

5 + 31458311 = 31458316
17 + 31458299 = 31458316
233 + 31458083 = 31458316
317 + 31457999 = 31458316
347 + 31457969 = 31458316
467 + 31457849 = 31458316
557 + 31457759 = 31458316
563 + 31457753 = 31458316

Showing the first eight; more decompositions exist.
