Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547350, here are decompositions:

  • 11 + 31547339 = 31547350
  • 47 + 31547303 = 31547350
  • 53 + 31547297 = 31547350
  • 83 + 31547267 = 31547350
  • 89 + 31547261 = 31547350
  • 173 + 31547177 = 31547350
  • 257 + 31547093 = 31547350
  • 311 + 31547039 = 31547350

Showing the first eight; more decompositions exist.
