Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475492, here are decompositions:

  • 5 + 2147475487 = 2147475492
  • 11 + 2147475481 = 2147475492
  • 53 + 2147475439 = 2147475492
  • 79 + 2147475413 = 2147475492
  • 223 + 2147475269 = 2147475492
  • 241 + 2147475251 = 2147475492
  • 263 + 2147475229 = 2147475492
  • 271 + 2147475221 = 2147475492

Showing the first eight; more decompositions exist.

IPv4 address
