Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702680, here are decompositions:

  • 17 + 8702663 = 8702680
  • 83 + 8702597 = 8702680
  • 89 + 8702591 = 8702680
  • 137 + 8702543 = 8702680
  • 191 + 8702489 = 8702680
  • 197 + 8702483 = 8702680
  • 269 + 8702411 = 8702680
  • 293 + 8702387 = 8702680

Showing the first eight; more decompositions exist.
