Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147571622, here are decompositions:

  • 89 + 2147571533 = 2147571622
  • 173 + 2147571449 = 2147571622
  • 359 + 2147571263 = 2147571622
  • 641 + 2147570981 = 2147571622
  • 701 + 2147570921 = 2147571622
  • 719 + 2147570903 = 2147571622
  • 761 + 2147570861 = 2147571622
  • 1013 + 2147570609 = 2147571622

Showing the first eight; more decompositions exist.
