Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641468, here are decompositions:

  • 47 + 8641421 = 8641468
  • 107 + 8641361 = 8641468
  • 137 + 8641331 = 8641468
  • 149 + 8641319 = 8641468
  • 167 + 8641301 = 8641468
  • 179 + 8641289 = 8641468
  • 257 + 8641211 = 8641468
  • 281 + 8641187 = 8641468

Showing the first eight; more decompositions exist.
