Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435566, here are decompositions:

  • 83 + 2147435483 = 2147435566
  • 149 + 2147435417 = 2147435566
  • 239 + 2147435327 = 2147435566
  • 317 + 2147435249 = 2147435566
  • 503 + 2147435063 = 2147435566
  • 509 + 2147435057 = 2147435566
  • 557 + 2147435009 = 2147435566
  • 587 + 2147434979 = 2147435566

Showing the first eight; more decompositions exist.
