Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994720, here are decompositions:

  • 7 + 4294994713 = 4294994720
  • 19 + 4294994701 = 4294994720
  • 103 + 4294994617 = 4294994720
  • 229 + 4294994491 = 4294994720
  • 271 + 4294994449 = 4294994720
  • 349 + 4294994371 = 4294994720
  • 409 + 4294994311 = 4294994720
  • 487 + 4294994233 = 4294994720

Showing the first eight; more decompositions exist.
