Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497742, here are decompositions:

  • 43 + 2147497699 = 2147497742
  • 79 + 2147497663 = 2147497742
  • 283 + 2147497459 = 2147497742
  • 331 + 2147497411 = 2147497742
  • 349 + 2147497393 = 2147497742
  • 421 + 2147497321 = 2147497742
  • 499 + 2147497243 = 2147497742
  • 541 + 2147497201 = 2147497742

Showing the first eight; more decompositions exist.
