Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467668, here are decompositions:

  • 29 + 2147467639 = 2147467668
  • 37 + 2147467631 = 2147467668
  • 41 + 2147467627 = 2147467668
  • 89 + 2147467579 = 2147467668
  • 109 + 2147467559 = 2147467668
  • 197 + 2147467471 = 2147467668
  • 337 + 2147467331 = 2147467668
  • 347 + 2147467321 = 2147467668

Showing the first eight; more decompositions exist.
