Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295071728, here are decompositions:

  • 7 + 4295071721 = 4295071728
  • 61 + 4295071667 = 4295071728
  • 137 + 4295071591 = 4295071728
  • 197 + 4295071531 = 4295071728
  • 271 + 4295071457 = 4295071728
  • 317 + 4295071411 = 4295071728
  • 379 + 4295071349 = 4295071728
  • 419 + 4295071309 = 4295071728

Showing the first eight; more decompositions exist.
