Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751828, here are decompositions:

  • 11 + 8751817 = 8751828
  • 47 + 8751781 = 8751828
  • 61 + 8751767 = 8751828
  • 79 + 8751749 = 8751828
  • 89 + 8751739 = 8751828
  • 101 + 8751727 = 8751828
  • 157 + 8751671 = 8751828
  • 199 + 8751629 = 8751828

Showing the first eight; more decompositions exist.
