Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673842, here are decompositions:

  • 3 + 8673839 = 8673842
  • 61 + 8673781 = 8673842
  • 139 + 8673703 = 8673842
  • 241 + 8673601 = 8673842
  • 271 + 8673571 = 8673842
  • 379 + 8673463 = 8673842
  • 409 + 8673433 = 8673842
  • 421 + 8673421 = 8673842

Showing the first eight; more decompositions exist.
