Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524230, here are decompositions:

  • 7 + 31524223 = 31524230
  • 37 + 31524193 = 31524230
  • 97 + 31524133 = 31524230
  • 139 + 31524091 = 31524230
  • 181 + 31524049 = 31524230
  • 277 + 31523953 = 31524230
  • 313 + 31523917 = 31524230
  • 349 + 31523881 = 31524230

Showing the first eight; more decompositions exist.
