Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740842, here are decompositions:

  • 43 + 8740799 = 8740842
  • 53 + 8740789 = 8740842
  • 59 + 8740783 = 8740842
  • 79 + 8740763 = 8740842
  • 163 + 8740679 = 8740842
  • 193 + 8740649 = 8740842
  • 199 + 8740643 = 8740842
  • 239 + 8740603 = 8740842

Showing the first eight; more decompositions exist.
