Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533000, here are decompositions:

  • 19 + 31532981 = 31533000
  • 29 + 31532971 = 31533000
  • 41 + 31532959 = 31533000
  • 61 + 31532939 = 31533000
  • 101 + 31532899 = 31533000
  • 127 + 31532873 = 31533000
  • 137 + 31532863 = 31533000
  • 167 + 31532833 = 31533000

Showing the first eight; more decompositions exist.
