Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639560, here are decompositions:

  • 11 + 8639549 = 8639560
  • 29 + 8639531 = 8639560
  • 53 + 8639507 = 8639560
  • 101 + 8639459 = 8639560
  • 107 + 8639453 = 8639560
  • 179 + 8639381 = 8639560
  • 197 + 8639363 = 8639560
  • 269 + 8639291 = 8639560

Showing the first eight; more decompositions exist.
