Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466858, here are decompositions:

  • 11 + 2147466847 = 2147466858
  • 71 + 2147466787 = 2147466858
  • 137 + 2147466721 = 2147466858
  • 157 + 2147466701 = 2147466858
  • 179 + 2147466679 = 2147466858
  • 269 + 2147466589 = 2147466858
  • 311 + 2147466547 = 2147466858
  • 337 + 2147466521 = 2147466858

Showing the first eight; more decompositions exist.
