Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499906, here are decompositions:

  • 23 + 2147499883 = 2147499906
  • 43 + 2147499863 = 2147499906
  • 179 + 2147499727 = 2147499906
  • 199 + 2147499707 = 2147499906
  • 359 + 2147499547 = 2147499906
  • 367 + 2147499539 = 2147499906
  • 373 + 2147499533 = 2147499906
  • 397 + 2147499509 = 2147499906

Showing the first eight; more decompositions exist.
