Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458946, here are decompositions:

23 + 31458923 = 31458946
83 + 31458863 = 31458946
149 + 31458797 = 31458946
227 + 31458719 = 31458946
257 + 31458689 = 31458946
353 + 31458593 = 31458946
359 + 31458587 = 31458946
419 + 31458527 = 31458946

Showing the first eight; more decompositions exist.
