Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458046, here are decompositions:

47 + 31457999 = 31458046
197 + 31457849 = 31458046
227 + 31457819 = 31458046
293 + 31457753 = 31458046
317 + 31457729 = 31458046
359 + 31457687 = 31458046
419 + 31457627 = 31458046
443 + 31457603 = 31458046

Showing the first eight; more decompositions exist.
