Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497540, here are decompositions:

  • 17 + 2147497523 = 2147497540
  • 47 + 2147497493 = 2147497540
  • 59 + 2147497481 = 2147497540
  • 137 + 2147497403 = 2147497540
  • 179 + 2147497361 = 2147497540
  • 191 + 2147497349 = 2147497540
  • 521 + 2147497019 = 2147497540
  • 569 + 2147496971 = 2147497540

Showing the first eight; more decompositions exist.
