Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718912, here are decompositions:

  • 5 + 8718907 = 8718912
  • 31 + 8718881 = 8718912
  • 43 + 8718869 = 8718912
  • 53 + 8718859 = 8718912
  • 61 + 8718851 = 8718912
  • 73 + 8718839 = 8718912
  • 79 + 8718833 = 8718912
  • 89 + 8718823 = 8718912

Showing the first eight; more decompositions exist.
