Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384474, here are decompositions:

  • 61 + 2147384413 = 2147384474
  • 211 + 2147384263 = 2147384474
  • 223 + 2147384251 = 2147384474
  • 271 + 2147384203 = 2147384474
  • 283 + 2147384191 = 2147384474
  • 457 + 2147384017 = 2147384474
  • 463 + 2147384011 = 2147384474
  • 601 + 2147383873 = 2147384474

Showing the first eight; more decompositions exist.
