Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647672, here are decompositions:

  • 83 + 8647589 = 8647672
  • 263 + 8647409 = 8647672
  • 281 + 8647391 = 8647672
  • 419 + 8647253 = 8647672
  • 443 + 8647229 = 8647672
  • 479 + 8647193 = 8647672
  • 491 + 8647181 = 8647672
  • 641 + 8647031 = 8647672

Showing the first eight; more decompositions exist.
