Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147455382, here are decompositions:

  • 19 + 2147455363 = 2147455382
  • 151 + 2147455231 = 2147455382
  • 271 + 2147455111 = 2147455382
  • 379 + 2147455003 = 2147455382
  • 409 + 2147454973 = 2147455382
  • 619 + 2147454763 = 2147455382
  • 739 + 2147454643 = 2147455382
  • 859 + 2147454523 = 2147455382

Showing the first eight; more decompositions exist.
