Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463912, here are decompositions:

  • 3 + 31463909 = 31463912
  • 19 + 31463893 = 31463912
  • 199 + 31463713 = 31463912
  • 223 + 31463689 = 31463912
  • 379 + 31463533 = 31463912
  • 523 + 31463389 = 31463912
  • 631 + 31463281 = 31463912
  • 643 + 31463269 = 31463912

Showing the first eight; more decompositions exist.
