Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486138, here are decompositions:

  • 139 + 2147485999 = 2147486138
  • 199 + 2147485939 = 2147486138
  • 211 + 2147485927 = 2147486138
  • 241 + 2147485897 = 2147486138
  • 271 + 2147485867 = 2147486138
  • 277 + 2147485861 = 2147486138
  • 331 + 2147485807 = 2147486138
  • 379 + 2147485759 = 2147486138

Showing the first eight; more decompositions exist.

IPv4 address
