Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147561582, here are decompositions:

  • 13 + 2147561569 = 2147561582
  • 43 + 2147561539 = 2147561582
  • 373 + 2147561209 = 2147561582
  • 421 + 2147561161 = 2147561582
  • 433 + 2147561149 = 2147561582
  • 631 + 2147560951 = 2147561582
  • 709 + 2147560873 = 2147561582
  • 739 + 2147560843 = 2147561582

Showing the first eight; more decompositions exist.
