Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479852, here are decompositions:

  • 29 + 2147479823 = 2147479852
  • 71 + 2147479781 = 2147479852
  • 101 + 2147479751 = 2147479852
  • 233 + 2147479619 = 2147479852
  • 251 + 2147479601 = 2147479852
  • 263 + 2147479589 = 2147479852
  • 431 + 2147479421 = 2147479852
  • 449 + 2147479403 = 2147479852

Showing the first eight; more decompositions exist.
