Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147557466, here are decompositions:

  • 3 + 2147557463 = 2147557466
  • 97 + 2147557369 = 2147557466
  • 127 + 2147557339 = 2147557466
  • 199 + 2147557267 = 2147557466
  • 337 + 2147557129 = 2147557466
  • 349 + 2147557117 = 2147557466
  • 463 + 2147557003 = 2147557466
  • 499 + 2147556967 = 2147557466

Showing the first eight; more decompositions exist.
