Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472582, here are decompositions:

  • 83 + 2147472499 = 2147472582
  • 113 + 2147472469 = 2147472582
  • 139 + 2147472443 = 2147472582
  • 239 + 2147472343 = 2147472582
  • 271 + 2147472311 = 2147472582
  • 293 + 2147472289 = 2147472582
  • 331 + 2147472251 = 2147472582
  • 383 + 2147472199 = 2147472582

Showing the first eight; more decompositions exist.
