Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499740, here are decompositions:

  • 13 + 2147499727 = 2147499740
  • 37 + 2147499703 = 2147499740
  • 163 + 2147499577 = 2147499740
  • 193 + 2147499547 = 2147499740
  • 229 + 2147499511 = 2147499740
  • 283 + 2147499457 = 2147499740
  • 307 + 2147499433 = 2147499740
  • 349 + 2147499391 = 2147499740

Showing the first eight; more decompositions exist.
