Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722006, here are decompositions:

  • 5 + 8722001 = 8722006
  • 17 + 8721989 = 8722006
  • 89 + 8721917 = 8722006
  • 233 + 8721773 = 8722006
  • 257 + 8721749 = 8722006
  • 269 + 8721737 = 8722006
  • 389 + 8721617 = 8722006
  • 467 + 8721539 = 8722006

Showing the first eight; more decompositions exist.
