Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967840, here are decompositions:

  • 19 + 4294967821 = 4294967840
  • 43 + 4294967797 = 4294967840
  • 61 + 4294967779 = 4294967840
  • 139 + 4294967701 = 4294967840
  • 271 + 4294967569 = 4294967840
  • 277 + 4294967563 = 4294967840
  • 463 + 4294967377 = 4294967840
  • 643 + 4294967197 = 4294967840

Showing the first eight; more decompositions exist.
