Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711580, here are decompositions:

  • 11 + 8711569 = 8711580
  • 19 + 8711561 = 8711580
  • 29 + 8711551 = 8711580
  • 37 + 8711543 = 8711580
  • 47 + 8711533 = 8711580
  • 79 + 8711501 = 8711580
  • 89 + 8711491 = 8711580
  • 113 + 8711467 = 8711580

Showing the first eight; more decompositions exist.
