Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524284, here are decompositions:

  • 7 + 31524277 = 31524284
  • 13 + 31524271 = 31524284
  • 61 + 31524223 = 31524284
  • 151 + 31524133 = 31524284
  • 193 + 31524091 = 31524284
  • 241 + 31524043 = 31524284
  • 271 + 31524013 = 31524284
  • 331 + 31523953 = 31524284

Showing the first eight; more decompositions exist.
