Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689240, here are decompositions:

  • 17 + 8689223 = 8689240
  • 23 + 8689217 = 8689240
  • 59 + 8689181 = 8689240
  • 71 + 8689169 = 8689240
  • 107 + 8689133 = 8689240
  • 431 + 8688809 = 8689240
  • 449 + 8688791 = 8689240
  • 569 + 8688671 = 8689240

Showing the first eight; more decompositions exist.
