Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547230, here are decompositions:

  • 53 + 31547177 = 31547230
  • 83 + 31547147 = 31547230
  • 101 + 31547129 = 31547230
  • 137 + 31547093 = 31547230
  • 167 + 31547063 = 31547230
  • 191 + 31547039 = 31547230
  • 227 + 31547003 = 31547230
  • 233 + 31546997 = 31547230

Showing the first eight; more decompositions exist.
