Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404690, here are decompositions:

  • 71 + 2147404619 = 2147404690
  • 89 + 2147404601 = 2147404690
  • 107 + 2147404583 = 2147404690
  • 113 + 2147404577 = 2147404690
  • 251 + 2147404439 = 2147404690
  • 359 + 2147404331 = 2147404690
  • 443 + 2147404247 = 2147404690
  • 461 + 2147404229 = 2147404690

Showing the first eight; more decompositions exist.
