Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459888, here are decompositions:

  • 29 + 31459859 = 31459888
  • 41 + 31459847 = 31459888
  • 59 + 31459829 = 31459888
  • 179 + 31459709 = 31459888
  • 191 + 31459697 = 31459888
  • 227 + 31459661 = 31459888
  • 269 + 31459619 = 31459888
  • 347 + 31459541 = 31459888

Showing the first eight; more decompositions exist.
