Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497700, here are decompositions:

  • 3 + 2147497697 = 2147497700
  • 37 + 2147497663 = 2147497700
  • 193 + 2147497507 = 2147497700
  • 211 + 2147497489 = 2147497700
  • 241 + 2147497459 = 2147497700
  • 307 + 2147497393 = 2147497700
  • 379 + 2147497321 = 2147497700
  • 457 + 2147497243 = 2147497700

Showing the first eight; more decompositions exist.
