Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147392582, here are decompositions:

  • 11 + 2147392571 = 2147392582
  • 113 + 2147392469 = 2147392582
  • 173 + 2147392409 = 2147392582
  • 191 + 2147392391 = 2147392582
  • 281 + 2147392301 = 2147392582
  • 311 + 2147392271 = 2147392582
  • 431 + 2147392151 = 2147392582
  • 443 + 2147392139 = 2147392582

Showing the first eight; more decompositions exist.
