Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57828, here are decompositions:

  • 19 + 57809 = 57828
  • 37 + 57791 = 57828
  • 41 + 57787 = 57828
  • 47 + 57781 = 57828
  • 97 + 57731 = 57828
  • 101 + 57727 = 57828
  • 109 + 57719 = 57828
  • 131 + 57697 = 57828

Showing the first eight; more decompositions exist.
