Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499800, here are decompositions:

  • 73 + 2147499727 = 2147499800
  • 97 + 2147499703 = 2147499800
  • 223 + 2147499577 = 2147499800
  • 349 + 2147499451 = 2147499800
  • 367 + 2147499433 = 2147499800
  • 409 + 2147499391 = 2147499800
  • 421 + 2147499379 = 2147499800
  • 547 + 2147499253 = 2147499800

Showing the first eight; more decompositions exist.
