Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532200, here are decompositions:

  • 59 + 31532141 = 31532200
  • 83 + 31532117 = 31532200
  • 137 + 31532063 = 31532200
  • 179 + 31532021 = 31532200
  • 197 + 31532003 = 31532200
  • 233 + 31531967 = 31532200
  • 269 + 31531931 = 31532200
  • 317 + 31531883 = 31532200

Showing the first eight; more decompositions exist.
