Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669520, here are decompositions:

  • 7 + 8669513 = 8669520
  • 19 + 8669501 = 8669520
  • 31 + 8669489 = 8669520
  • 37 + 8669483 = 8669520
  • 43 + 8669477 = 8669520
  • 73 + 8669447 = 8669520
  • 103 + 8669417 = 8669520
  • 109 + 8669411 = 8669520

Showing the first eight; more decompositions exist.
