Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459006, here are decompositions:

23 + 31458983 = 31459006
53 + 31458953 = 31459006
83 + 31458923 = 31459006
317 + 31458689 = 31459006
419 + 31458587 = 31459006
479 + 31458527 = 31459006
569 + 31458437 = 31459006
587 + 31458419 = 31459006

Showing the first eight; more decompositions exist.
