Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82160, here are decompositions:

  • 7 + 82153 = 82160
  • 19 + 82141 = 82160
  • 31 + 82129 = 82160
  • 109 + 82051 = 82160
  • 139 + 82021 = 82160
  • 151 + 82009 = 82160
  • 157 + 82003 = 82160
  • 193 + 81967 = 82160

Showing the first eight; more decompositions exist.
