Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741840, here are decompositions:

  • 43 + 8741797 = 8741840
  • 61 + 8741779 = 8741840
  • 97 + 8741743 = 8741840
  • 157 + 8741683 = 8741840
  • 199 + 8741641 = 8741840
  • 277 + 8741563 = 8741840
  • 307 + 8741533 = 8741840
  • 337 + 8741503 = 8741840

Showing the first eight; more decompositions exist.
