Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466884, here are decompositions:

  • 37 + 2147466847 = 2147466884
  • 97 + 2147466787 = 2147466884
  • 163 + 2147466721 = 2147466884
  • 337 + 2147466547 = 2147466884
  • 397 + 2147466487 = 2147466884
  • 421 + 2147466463 = 2147466884
  • 457 + 2147466427 = 2147466884
  • 547 + 2147466337 = 2147466884

Showing the first eight; more decompositions exist.
