Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599820, here are decompositions:

  • 3 + 8599817 = 8599820
  • 127 + 8599693 = 8599820
  • 241 + 8599579 = 8599820
  • 331 + 8599489 = 8599820
  • 349 + 8599471 = 8599820
  • 367 + 8599453 = 8599820
  • 409 + 8599411 = 8599820
  • 457 + 8599363 = 8599820

Showing the first eight; more decompositions exist.
