Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547266, here are decompositions:

  • 5 + 31547261 = 31547266
  • 89 + 31547177 = 31547266
  • 137 + 31547129 = 31547266
  • 173 + 31547093 = 31547266
  • 227 + 31547039 = 31547266
  • 263 + 31547003 = 31547266
  • 269 + 31546997 = 31547266
  • 353 + 31546913 = 31547266

Showing the first eight; more decompositions exist.
