Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466648, here are decompositions:

  • 7 + 2147466641 = 2147466648
  • 59 + 2147466589 = 2147466648
  • 101 + 2147466547 = 2147466648
  • 109 + 2147466539 = 2147466648
  • 127 + 2147466521 = 2147466648
  • 191 + 2147466457 = 2147466648
  • 199 + 2147466449 = 2147466648
  • 311 + 2147466337 = 2147466648

Showing the first eight; more decompositions exist.
