Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475380, here are decompositions:

  • 7 + 2147475373 = 2147475380
  • 13 + 2147475367 = 2147475380
  • 31 + 2147475349 = 2147475380
  • 103 + 2147475277 = 2147475380
  • 151 + 2147475229 = 2147475380
  • 199 + 2147475181 = 2147475380
  • 277 + 2147475103 = 2147475380
  • 433 + 2147474947 = 2147475380

Showing the first eight; more decompositions exist.

IPv4 address
