Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978664, here are decompositions:

  • 3 + 4294978661 = 4294978664
  • 37 + 4294978627 = 4294978664
  • 73 + 4294978591 = 4294978664
  • 283 + 4294978381 = 4294978664
  • 331 + 4294978333 = 4294978664
  • 337 + 4294978327 = 4294978664
  • 433 + 4294978231 = 4294978664
  • 463 + 4294978201 = 4294978664

Showing the first eight; more decompositions exist.
