Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725900, here are decompositions:

  • 23 + 8725877 = 8725900
  • 59 + 8725841 = 8725900
  • 83 + 8725817 = 8725900
  • 101 + 8725799 = 8725900
  • 167 + 8725733 = 8725900
  • 257 + 8725643 = 8725900
  • 269 + 8725631 = 8725900
  • 353 + 8725547 = 8725900

Showing the first eight; more decompositions exist.
