Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718864, here are decompositions:

  • 5 + 8718859 = 8718864
  • 13 + 8718851 = 8718864
  • 31 + 8718833 = 8718864
  • 41 + 8718823 = 8718864
  • 53 + 8718811 = 8718864
  • 61 + 8718803 = 8718864
  • 67 + 8718797 = 8718864
  • 71 + 8718793 = 8718864

Showing the first eight; more decompositions exist.
