Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75120, here are decompositions:

  • 11 + 75109 = 75120
  • 37 + 75083 = 75120
  • 41 + 75079 = 75120
  • 79 + 75041 = 75120
  • 83 + 75037 = 75120
  • 103 + 75017 = 75120
  • 107 + 75013 = 75120
  • 109 + 75011 = 75120

Showing the first eight; more decompositions exist.
