Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669864, here are decompositions:

  • 3 + 8669861 = 8669864
  • 43 + 8669821 = 8669864
  • 97 + 8669767 = 8669864
  • 163 + 8669701 = 8669864
  • 193 + 8669671 = 8669864
  • 241 + 8669623 = 8669864
  • 271 + 8669593 = 8669864
  • 337 + 8669527 = 8669864

Showing the first eight; more decompositions exist.
