Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497936, here are decompositions:

  • 29 + 2147497907 = 2147497936
  • 47 + 2147497889 = 2147497936
  • 167 + 2147497769 = 2147497936
  • 179 + 2147497757 = 2147497936
  • 239 + 2147497697 = 2147497936
  • 443 + 2147497493 = 2147497936
  • 587 + 2147497349 = 2147497936
  • 1019 + 2147496917 = 2147497936

Showing the first eight; more decompositions exist.
