Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481828, here are decompositions:

  • 17 + 2147481811 = 2147481828
  • 31 + 2147481797 = 2147481828
  • 199 + 2147481629 = 2147481828
  • 257 + 2147481571 = 2147481828
  • 337 + 2147481491 = 2147481828
  • 461 + 2147481367 = 2147481828
  • 491 + 2147481337 = 2147481828
  • 619 + 2147481209 = 2147481828

Showing the first eight; more decompositions exist.
