Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497982, here are decompositions:

  • 43 + 2147497939 = 2147497982
  • 61 + 2147497921 = 2147497982
  • 211 + 2147497771 = 2147497982
  • 283 + 2147497699 = 2147497982
  • 523 + 2147497459 = 2147497982
  • 571 + 2147497411 = 2147497982
  • 661 + 2147497321 = 2147497982
  • 739 + 2147497243 = 2147497982

Showing the first eight; more decompositions exist.
