Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72200, here are decompositions:

  • 31 + 72169 = 72200
  • 61 + 72139 = 72200
  • 97 + 72103 = 72200
  • 109 + 72091 = 72200
  • 127 + 72073 = 72200
  • 157 + 72043 = 72200
  • 181 + 72019 = 72200
  • 229 + 71971 = 72200

Showing the first eight; more decompositions exist.
