Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467568, here are decompositions:

  • 97 + 2147467471 = 2147467568
  • 229 + 2147467339 = 2147467568
  • 241 + 2147467327 = 2147467568
  • 307 + 2147467261 = 2147467568
  • 349 + 2147467219 = 2147467568
  • 577 + 2147466991 = 2147467568
  • 1021 + 2147466547 = 2147467568
  • 1129 + 2147466439 = 2147467568

Showing the first eight; more decompositions exist.
