Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990720, here are decompositions:

  • 29 + 4294990691 = 4294990720
  • 89 + 4294990631 = 4294990720
  • 191 + 4294990529 = 4294990720
  • 257 + 4294990463 = 4294990720
  • 311 + 4294990409 = 4294990720
  • 359 + 4294990361 = 4294990720
  • 431 + 4294990289 = 4294990720
  • 479 + 4294990241 = 4294990720

Showing the first eight; more decompositions exist.
