Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978266, here are decompositions:

  • 17 + 4294978249 = 4294978266
  • 43 + 4294978223 = 4294978266
  • 97 + 4294978169 = 4294978266
  • 109 + 4294978157 = 4294978266
  • 179 + 4294978087 = 4294978266
  • 199 + 4294978067 = 4294978266
  • 233 + 4294978033 = 4294978266
  • 239 + 4294978027 = 4294978266

Showing the first eight; more decompositions exist.
