Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27786, here are decompositions:

  • 7 + 27779 = 27786
  • 13 + 27773 = 27786
  • 19 + 27767 = 27786
  • 23 + 27763 = 27786
  • 37 + 27749 = 27786
  • 43 + 27743 = 27786
  • 47 + 27739 = 27786
  • 53 + 27733 = 27786

Showing the first eight; more decompositions exist.
