Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147563982, here are decompositions:

  • 19 + 2147563963 = 2147563982
  • 163 + 2147563819 = 2147563982
  • 211 + 2147563771 = 2147563982
  • 229 + 2147563753 = 2147563982
  • 241 + 2147563741 = 2147563982
  • 349 + 2147563633 = 2147563982
  • 463 + 2147563519 = 2147563982
  • 523 + 2147563459 = 2147563982

Showing the first eight; more decompositions exist.
