Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978408, here are decompositions:

  • 47 + 4294978361 = 4294978408
  • 101 + 4294978307 = 4294978408
  • 197 + 4294978211 = 4294978408
  • 239 + 4294978169 = 4294978408
  • 251 + 4294978157 = 4294978408
  • 317 + 4294978091 = 4294978408
  • 419 + 4294977989 = 4294978408
  • 509 + 4294977899 = 4294978408

Showing the first eight; more decompositions exist.
