Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978660, here are decompositions:

  • 101 + 4294978559 = 4294978660
  • 107 + 4294978553 = 4294978660
  • 149 + 4294978511 = 4294978660
  • 347 + 4294978313 = 4294978660
  • 353 + 4294978307 = 4294978660
  • 449 + 4294978211 = 4294978660
  • 491 + 4294978169 = 4294978660
  • 503 + 4294978157 = 4294978660

Showing the first eight; more decompositions exist.
