Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147390926, here are decompositions:

  • 3 + 2147390923 = 2147390926
  • 29 + 2147390897 = 2147390926
  • 53 + 2147390873 = 2147390926
  • 137 + 2147390789 = 2147390926
  • 269 + 2147390657 = 2147390926
  • 479 + 2147390447 = 2147390926
  • 563 + 2147390363 = 2147390926
  • 599 + 2147390327 = 2147390926

Showing the first eight; more decompositions exist.
