Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669892, here are decompositions:

  • 13 + 8669879 = 8669892
  • 31 + 8669861 = 8669892
  • 61 + 8669831 = 8669892
  • 71 + 8669821 = 8669892
  • 191 + 8669701 = 8669892
  • 223 + 8669669 = 8669892
  • 241 + 8669651 = 8669892
  • 263 + 8669629 = 8669892

Showing the first eight; more decompositions exist.
