Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466872, here are decompositions:

  • 3 + 2147466869 = 2147466872
  • 79 + 2147466793 = 2147466872
  • 151 + 2147466721 = 2147466872
  • 193 + 2147466679 = 2147466872
  • 283 + 2147466589 = 2147466872
  • 409 + 2147466463 = 2147466872
  • 433 + 2147466439 = 2147466872
  • 571 + 2147466301 = 2147466872

Showing the first eight; more decompositions exist.
