Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751742, here are decompositions:

  • 3 + 8751739 = 8751742
  • 71 + 8751671 = 8751742
  • 113 + 8751629 = 8751742
  • 149 + 8751593 = 8751742
  • 179 + 8751563 = 8751742
  • 239 + 8751503 = 8751742
  • 281 + 8751461 = 8751742
  • 401 + 8751341 = 8751742

Showing the first eight; more decompositions exist.
