Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86180, here are decompositions:

  • 19 + 86161 = 86180
  • 37 + 86143 = 86180
  • 43 + 86137 = 86180
  • 67 + 86113 = 86180
  • 97 + 86083 = 86180
  • 103 + 86077 = 86180
  • 151 + 86029 = 86180
  • 163 + 86017 = 86180

Showing the first eight; more decompositions exist.
