Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473388, here are decompositions:

  • 19 + 2147473369 = 2147473388
  • 37 + 2147473351 = 2147473388
  • 97 + 2147473291 = 2147473388
  • 157 + 2147473231 = 2147473388
  • 271 + 2147473117 = 2147473388
  • 601 + 2147472787 = 2147473388
  • 631 + 2147472757 = 2147473388
  • 691 + 2147472697 = 2147473388

Showing the first eight; more decompositions exist.
