Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85000, here are decompositions:

  • 23 + 84977 = 85000
  • 53 + 84947 = 85000
  • 131 + 84869 = 85000
  • 173 + 84827 = 85000
  • 191 + 84809 = 85000
  • 239 + 84761 = 85000
  • 263 + 84737 = 85000
  • 269 + 84731 = 85000

Showing the first eight; more decompositions exist.
