Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473312, here are decompositions:

  • 11 + 2147473301 = 2147473312
  • 29 + 2147473283 = 2147473312
  • 71 + 2147473241 = 2147473312
  • 191 + 2147473121 = 2147473312
  • 251 + 2147473061 = 2147473312
  • 263 + 2147473049 = 2147473312
  • 353 + 2147472959 = 2147473312
  • 389 + 2147472923 = 2147473312

Showing the first eight; more decompositions exist.
