Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80000, here are decompositions:

  • 3 + 79997 = 80000
  • 13 + 79987 = 80000
  • 61 + 79939 = 80000
  • 97 + 79903 = 80000
  • 127 + 79873 = 80000
  • 139 + 79861 = 80000
  • 157 + 79843 = 80000
  • 199 + 79801 = 80000

Showing the first eight; more decompositions exist.
