Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27812, here are decompositions:

  • 3 + 27809 = 27812
  • 13 + 27799 = 27812
  • 19 + 27793 = 27812
  • 61 + 27751 = 27812
  • 73 + 27739 = 27812
  • 79 + 27733 = 27812
  • 139 + 27673 = 27812
  • 181 + 27631 = 27812

Showing the first eight; more decompositions exist.
