Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71886, here are decompositions:

  • 5 + 71881 = 71886
  • 7 + 71879 = 71886
  • 19 + 71867 = 71886
  • 37 + 71849 = 71886
  • 43 + 71843 = 71886
  • 79 + 71807 = 71886
  • 97 + 71789 = 71886
  • 109 + 71777 = 71886

Showing the first eight; more decompositions exist.
