Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458982, here are decompositions:

29 + 31458953 = 31458982
59 + 31458923 = 31458982
263 + 31458719 = 31458982
281 + 31458701 = 31458982
293 + 31458689 = 31458982
389 + 31458593 = 31458982
563 + 31458419 = 31458982
683 + 31458299 = 31458982

Showing the first eight; more decompositions exist.
