Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472634, here are decompositions:

  • 17 + 2147472617 = 2147472634
  • 23 + 2147472611 = 2147472634
  • 191 + 2147472443 = 2147472634
  • 257 + 2147472377 = 2147472634
  • 383 + 2147472251 = 2147472634
  • 491 + 2147472143 = 2147472634
  • 563 + 2147472071 = 2147472634
  • 641 + 2147471993 = 2147472634

Showing the first eight; more decompositions exist.
