Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978866, here are decompositions:

  • 67 + 4294978799 = 4294978866
  • 89 + 4294978777 = 4294978866
  • 109 + 4294978757 = 4294978866
  • 137 + 4294978729 = 4294978866
  • 239 + 4294978627 = 4294978866
  • 307 + 4294978559 = 4294978866
  • 313 + 4294978553 = 4294978866
  • 349 + 4294978517 = 4294978866

Showing the first eight; more decompositions exist.
