Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477180, here are decompositions:

  • 67 + 2147477113 = 2147477180
  • 73 + 2147477107 = 2147477180
  • 151 + 2147477029 = 2147477180
  • 229 + 2147476951 = 2147477180
  • 283 + 2147476897 = 2147477180
  • 439 + 2147476741 = 2147477180
  • 487 + 2147476693 = 2147477180
  • 661 + 2147476519 = 2147477180

Showing the first eight; more decompositions exist.
