Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499794, here are decompositions:

  • 67 + 2147499727 = 2147499794
  • 283 + 2147499511 = 2147499794
  • 313 + 2147499481 = 2147499794
  • 337 + 2147499457 = 2147499794
  • 541 + 2147499253 = 2147499794
  • 577 + 2147499217 = 2147499794
  • 757 + 2147499037 = 2147499794
  • 877 + 2147498917 = 2147499794

Showing the first eight; more decompositions exist.
