Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646100, here are decompositions:

  • 41 + 8646059 = 8646100
  • 83 + 8646017 = 8646100
  • 173 + 8645927 = 8646100
  • 251 + 8645849 = 8646100
  • 311 + 8645789 = 8646100
  • 431 + 8645669 = 8646100
  • 443 + 8645657 = 8646100
  • 467 + 8645633 = 8646100

Showing the first eight; more decompositions exist.
