Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497926, here are decompositions:

  • 5 + 2147497921 = 2147497926
  • 19 + 2147497907 = 2147497926
  • 37 + 2147497889 = 2147497926
  • 157 + 2147497769 = 2147497926
  • 193 + 2147497733 = 2147497926
  • 227 + 2147497699 = 2147497926
  • 229 + 2147497697 = 2147497926
  • 263 + 2147497663 = 2147497926

Showing the first eight; more decompositions exist.
