Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740820, here are decompositions:

  • 13 + 8740807 = 8740820
  • 31 + 8740789 = 8740820
  • 37 + 8740783 = 8740820
  • 139 + 8740681 = 8740820
  • 163 + 8740657 = 8740820
  • 229 + 8740591 = 8740820
  • 241 + 8740579 = 8740820
  • 367 + 8740453 = 8740820

Showing the first eight; more decompositions exist.
