Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978782, here are decompositions:

  • 5 + 4294978777 = 4294978782
  • 53 + 4294978729 = 4294978782
  • 103 + 4294978679 = 4294978782
  • 191 + 4294978591 = 4294978782
  • 223 + 4294978559 = 4294978782
  • 229 + 4294978553 = 4294978782
  • 271 + 4294978511 = 4294978782
  • 293 + 4294978489 = 4294978782

Showing the first eight; more decompositions exist.
