Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978392, here are decompositions:

  • 11 + 4294978381 = 4294978392
  • 31 + 4294978361 = 4294978392
  • 59 + 4294978333 = 4294978392
  • 79 + 4294978313 = 4294978392
  • 83 + 4294978309 = 4294978392
  • 109 + 4294978283 = 4294978392
  • 181 + 4294978211 = 4294978392
  • 191 + 4294978201 = 4294978392

Showing the first eight; more decompositions exist.
