Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665960, here are decompositions:

  • 11 + 8665949 = 8665960
  • 29 + 8665931 = 8665960
  • 47 + 8665913 = 8665960
  • 71 + 8665889 = 8665960
  • 257 + 8665703 = 8665960
  • 293 + 8665667 = 8665960
  • 311 + 8665649 = 8665960
  • 389 + 8665571 = 8665960

Showing the first eight; more decompositions exist.
