Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502520, here are decompositions:

  • 3 + 33502517 = 33502520
  • 31 + 33502489 = 33502520
  • 43 + 33502477 = 33502520
  • 157 + 33502363 = 33502520
  • 193 + 33502327 = 33502520
  • 199 + 33502321 = 33502520
  • 223 + 33502297 = 33502520
  • 277 + 33502243 = 33502520

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.53.56.
