Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524200, here are decompositions:

  • 3 + 31524197 = 31524200
  • 7 + 31524193 = 31524200
  • 67 + 31524133 = 31524200
  • 109 + 31524091 = 31524200
  • 151 + 31524049 = 31524200
  • 157 + 31524043 = 31524200
  • 283 + 31523917 = 31524200
  • 349 + 31523851 = 31524200

Showing the first eight; more decompositions exist.
