Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472666, here are decompositions:

  • 7 + 2147472659 = 2147472666
  • 109 + 2147472557 = 2147472666
  • 167 + 2147472499 = 2147472666
  • 197 + 2147472469 = 2147472666
  • 223 + 2147472443 = 2147472666
  • 293 + 2147472373 = 2147472666
  • 467 + 2147472199 = 2147472666
  • 523 + 2147472143 = 2147472666

Showing the first eight; more decompositions exist.
