Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623828, here are decompositions:

  • 29 + 8623799 = 8623828
  • 41 + 8623787 = 8623828
  • 71 + 8623757 = 8623828
  • 107 + 8623721 = 8623828
  • 149 + 8623679 = 8623828
  • 167 + 8623661 = 8623828
  • 281 + 8623547 = 8623828
  • 419 + 8623409 = 8623828

Showing the first eight; more decompositions exist.
