Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468278, here are decompositions:

  • 29 + 2147468249 = 2147468278
  • 47 + 2147468231 = 2147468278
  • 89 + 2147468189 = 2147468278
  • 311 + 2147467967 = 2147468278
  • 359 + 2147467919 = 2147468278
  • 509 + 2147467769 = 2147468278
  • 647 + 2147467631 = 2147468278
  • 719 + 2147467559 = 2147468278

Showing the first eight; more decompositions exist.
