Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127902, here are decompositions:

  • 29 + 127873 = 127902
  • 43 + 127859 = 127902
  • 53 + 127849 = 127902
  • 59 + 127843 = 127902
  • 83 + 127819 = 127902
  • 139 + 127763 = 127902
  • 163 + 127739 = 127902
  • 191 + 127711 = 127902

Showing the first eight; more decompositions exist.
