Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732880, here are decompositions:

  • 11 + 8732869 = 8732880
  • 19 + 8732861 = 8732880
  • 41 + 8732839 = 8732880
  • 47 + 8732833 = 8732880
  • 61 + 8732819 = 8732880
  • 73 + 8732807 = 8732880
  • 83 + 8732797 = 8732880
  • 131 + 8732749 = 8732880

Showing the first eight; more decompositions exist.
