Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978690, here are decompositions:

  • 11 + 4294978679 = 4294978690
  • 29 + 4294978661 = 4294978690
  • 131 + 4294978559 = 4294978690
  • 137 + 4294978553 = 4294978690
  • 173 + 4294978517 = 4294978690
  • 179 + 4294978511 = 4294978690
  • 383 + 4294978307 = 4294978690
  • 467 + 4294978223 = 4294978690

Showing the first eight; more decompositions exist.
