Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81088, here are decompositions:

  • 5 + 81083 = 81088
  • 11 + 81077 = 81088
  • 17 + 81071 = 81088
  • 41 + 81047 = 81088
  • 47 + 81041 = 81088
  • 71 + 81017 = 81088
  • 179 + 80909 = 81088
  • 191 + 80897 = 81088

Showing the first eight; more decompositions exist.
