Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27860, here are decompositions:

  • 13 + 27847 = 27860
  • 37 + 27823 = 27860
  • 43 + 27817 = 27860
  • 61 + 27799 = 27860
  • 67 + 27793 = 27860
  • 97 + 27763 = 27860
  • 109 + 27751 = 27860
  • 127 + 27733 = 27860

Showing the first eight; more decompositions exist.
