Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616556, here are decompositions:

  • 17 + 31616539 = 31616556
  • 47 + 31616509 = 31616556
  • 137 + 31616419 = 31616556
  • 163 + 31616393 = 31616556
  • 193 + 31616363 = 31616556
  • 197 + 31616359 = 31616556
  • 229 + 31616327 = 31616556
  • 269 + 31616287 = 31616556

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.110.44.

Address
1.226.110.44
Class
public
IPv4-mapped IPv6
::ffff:1.226.110.44

Public, routable address (assignable to a host on the internet).

Position in π

The digit sequence 31616556 first appears in π at position 110,725 of the decimal expansion (the 110,725ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
