Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147569904, here are decompositions:

  • 157 + 2147569747 = 2147569904
  • 223 + 2147569681 = 2147569904
  • 241 + 2147569663 = 2147569904
  • 331 + 2147569573 = 2147569904
  • 367 + 2147569537 = 2147569904
  • 373 + 2147569531 = 2147569904
  • 421 + 2147569483 = 2147569904
  • 463 + 2147569441 = 2147569904

Showing the first eight; more decompositions exist.
