Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978608, here are decompositions:

  • 17 + 4294978591 = 4294978608
  • 97 + 4294978511 = 4294978608
  • 227 + 4294978381 = 4294978608
  • 281 + 4294978327 = 4294978608
  • 359 + 4294978249 = 4294978608
  • 397 + 4294978211 = 4294978608
  • 439 + 4294978169 = 4294978608
  • 461 + 4294978147 = 4294978608

Showing the first eight; more decompositions exist.
