Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978998, here are decompositions:

  • 131 + 4294978867 = 4294978998
  • 199 + 4294978799 = 4294978998
  • 241 + 4294978757 = 4294978998
  • 269 + 4294978729 = 4294978998
  • 337 + 4294978661 = 4294978998
  • 439 + 4294978559 = 4294978998
  • 487 + 4294978511 = 4294978998
  • 509 + 4294978489 = 4294978998

Showing the first eight; more decompositions exist.
