Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647902, here are decompositions:

  • 5 + 8647897 = 8647902
  • 13 + 8647889 = 8647902
  • 23 + 8647879 = 8647902
  • 79 + 8647823 = 8647902
  • 83 + 8647819 = 8647902
  • 101 + 8647801 = 8647902
  • 149 + 8647753 = 8647902
  • 163 + 8647739 = 8647902

Showing the first eight; more decompositions exist.
