Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621746, here are decompositions:

  • 53 + 8621693 = 8621746
  • 137 + 8621609 = 8621746
  • 269 + 8621477 = 8621746
  • 293 + 8621453 = 8621746
  • 317 + 8621429 = 8621746
  • 503 + 8621243 = 8621746
  • 509 + 8621237 = 8621746
  • 557 + 8621189 = 8621746

Showing the first eight; more decompositions exist.
