Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429600, here are decompositions:

  • 37 + 2147429563 = 2147429600
  • 367 + 2147429233 = 2147429600
  • 577 + 2147429023 = 2147429600
  • 601 + 2147428999 = 2147429600
  • 619 + 2147428981 = 2147429600
  • 643 + 2147428957 = 2147429600
  • 709 + 2147428891 = 2147429600
  • 739 + 2147428861 = 2147429600

Showing the first eight; more decompositions exist.
