Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719320, here are decompositions:

  • 13 + 8719307 = 8719320
  • 17 + 8719303 = 8719320
  • 19 + 8719301 = 8719320
  • 31 + 8719289 = 8719320
  • 47 + 8719273 = 8719320
  • 59 + 8719261 = 8719320
  • 67 + 8719253 = 8719320
  • 97 + 8719223 = 8719320

Showing the first eight; more decompositions exist.
