Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479796, here are decompositions:

  • 43 + 2147479753 = 2147479796
  • 139 + 2147479657 = 2147479796
  • 223 + 2147479573 = 2147479796
  • 283 + 2147479513 = 2147479796
  • 307 + 2147479489 = 2147479796
  • 349 + 2147479447 = 2147479796
  • 457 + 2147479339 = 2147479796
  • 523 + 2147479273 = 2147479796

Showing the first eight; more decompositions exist.
