Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497740, here are decompositions:

  • 7 + 2147497733 = 2147497740
  • 23 + 2147497717 = 2147497740
  • 41 + 2147497699 = 2147497740
  • 43 + 2147497697 = 2147497740
  • 79 + 2147497661 = 2147497740
  • 181 + 2147497559 = 2147497740
  • 233 + 2147497507 = 2147497740
  • 251 + 2147497489 = 2147497740

Showing the first eight; more decompositions exist.
