Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466842, here are decompositions:

  • 163 + 2147466679 = 2147466842
  • 379 + 2147466463 = 2147466842
  • 523 + 2147466319 = 2147466842
  • 541 + 2147466301 = 2147466842
  • 613 + 2147466229 = 2147466842
  • 751 + 2147466091 = 2147466842
  • 769 + 2147466073 = 2147466842
  • 823 + 2147466019 = 2147466842

Showing the first eight; more decompositions exist.
