Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47902, here are decompositions:

  • 59 + 47843 = 47902
  • 83 + 47819 = 47902
  • 191 + 47711 = 47902
  • 263 + 47639 = 47902
  • 293 + 47609 = 47902
  • 311 + 47591 = 47902
  • 359 + 47543 = 47902
  • 389 + 47513 = 47902

Showing the first eight; more decompositions exist.
