Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967644, here are decompositions:

  • 5 + 4294967639 = 4294967644
  • 17 + 4294967627 = 4294967644
  • 47 + 4294967597 = 4294967644
  • 83 + 4294967561 = 4294967644
  • 101 + 4294967543 = 4294967644
  • 131 + 4294967513 = 4294967644
  • 167 + 4294967477 = 4294967644
  • 257 + 4294967387 = 4294967644

Showing the first eight; more decompositions exist.
