Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656670, here are decompositions:

  • 3 + 8656667 = 8656670
  • 67 + 8656603 = 8656670
  • 97 + 8656573 = 8656670
  • 109 + 8656561 = 8656670
  • 193 + 8656477 = 8656670
  • 271 + 8656399 = 8656670
  • 277 + 8656393 = 8656670
  • 307 + 8656363 = 8656670

Showing the first eight; more decompositions exist.
