Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47858, here are decompositions:

  • 61 + 47797 = 47858
  • 67 + 47791 = 47858
  • 79 + 47779 = 47858
  • 157 + 47701 = 47858
  • 199 + 47659 = 47858
  • 229 + 47629 = 47858
  • 277 + 47581 = 47858
  • 331 + 47527 = 47858

Showing the first eight; more decompositions exist.
