Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71896, here are decompositions:

  • 17 + 71879 = 71896
  • 29 + 71867 = 71896
  • 47 + 71849 = 71896
  • 53 + 71843 = 71896
  • 59 + 71837 = 71896
  • 89 + 71807 = 71896
  • 107 + 71789 = 71896
  • 197 + 71699 = 71896

Showing the first eight; more decompositions exist.
