Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404624, here are decompositions:

  • 3 + 2147404621 = 2147404624
  • 5 + 2147404619 = 2147404624
  • 23 + 2147404601 = 2147404624
  • 41 + 2147404583 = 2147404624
  • 47 + 2147404577 = 2147404624
  • 293 + 2147404331 = 2147404624
  • 467 + 2147404157 = 2147404624
  • 503 + 2147404121 = 2147404624

Showing the first eight; more decompositions exist.
