Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617420, here are decompositions:

  • 3 + 8617417 = 8617420
  • 23 + 8617397 = 8617420
  • 29 + 8617391 = 8617420
  • 47 + 8617373 = 8617420
  • 59 + 8617361 = 8617420
  • 101 + 8617319 = 8617420
  • 107 + 8617313 = 8617420
  • 167 + 8617253 = 8617420

Showing the first eight; more decompositions exist.
