Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704690, here are decompositions:

  • 3 + 8704687 = 8704690
  • 83 + 8704607 = 8704690
  • 89 + 8704601 = 8704690
  • 101 + 8704589 = 8704690
  • 131 + 8704559 = 8704690
  • 167 + 8704523 = 8704690
  • 191 + 8704499 = 8704690
  • 257 + 8704433 = 8704690

Showing the first eight; more decompositions exist.
