Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707940, here are decompositions:

  • 37 + 8707903 = 8707940
  • 61 + 8707879 = 8707940
  • 67 + 8707873 = 8707940
  • 79 + 8707861 = 8707940
  • 97 + 8707843 = 8707940
  • 103 + 8707837 = 8707940
  • 193 + 8707747 = 8707940
  • 229 + 8707711 = 8707940

Showing the first eight; more decompositions exist.
