Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618904, here are decompositions:

  • 11 + 8618893 = 8618904
  • 37 + 8618867 = 8618904
  • 43 + 8618861 = 8618904
  • 53 + 8618851 = 8618904
  • 71 + 8618833 = 8618904
  • 157 + 8618747 = 8618904
  • 167 + 8618737 = 8618904
  • 223 + 8618681 = 8618904

Showing the first eight; more decompositions exist.
