Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757120, here are decompositions:

  • 7 + 8757113 = 8757120
  • 11 + 8757109 = 8757120
  • 13 + 8757107 = 8757120
  • 37 + 8757083 = 8757120
  • 59 + 8757061 = 8757120
  • 61 + 8757059 = 8757120
  • 67 + 8757053 = 8757120
  • 79 + 8757041 = 8757120

Showing the first eight; more decompositions exist.
