Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57240, here are decompositions:

  • 17 + 57223 = 57240
  • 19 + 57221 = 57240
  • 37 + 57203 = 57240
  • 47 + 57193 = 57240
  • 61 + 57179 = 57240
  • 67 + 57173 = 57240
  • 97 + 57143 = 57240
  • 101 + 57139 = 57240

Showing the first eight; more decompositions exist.
