Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993720, here are decompositions:

  • 29 + 4294993691 = 4294993720
  • 53 + 4294993667 = 4294993720
  • 71 + 4294993649 = 4294993720
  • 113 + 4294993607 = 4294993720
  • 197 + 4294993523 = 4294993720
  • 317 + 4294993403 = 4294993720
  • 431 + 4294993289 = 4294993720
  • 593 + 4294993127 = 4294993720

Showing the first eight; more decompositions exist.
