Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399002, here are decompositions:

  • 5 + 2147398997 = 2147399002
  • 53 + 2147398949 = 2147399002
  • 83 + 2147398919 = 2147399002
  • 233 + 2147398769 = 2147399002
  • 443 + 2147398559 = 2147399002
  • 449 + 2147398553 = 2147399002
  • 641 + 2147398361 = 2147399002
  • 719 + 2147398283 = 2147399002

Showing the first eight; more decompositions exist.
