Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459168, here are decompositions:

  • 17 + 31459151 = 31459168
  • 137 + 31459031 = 31459168
  • 149 + 31459019 = 31459168
  • 347 + 31458821 = 31459168
  • 449 + 31458719 = 31459168
  • 467 + 31458701 = 31459168
  • 479 + 31458689 = 31459168
  • 641 + 31458527 = 31459168

Showing the first eight; more decompositions exist.
