Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670680, here are decompositions:

  • 13 + 8670667 = 8670680
  • 43 + 8670637 = 8670680
  • 61 + 8670619 = 8670680
  • 97 + 8670583 = 8670680
  • 127 + 8670553 = 8670680
  • 157 + 8670523 = 8670680
  • 181 + 8670499 = 8670680
  • 199 + 8670481 = 8670680

Showing the first eight; more decompositions exist.
