Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466788, here are decompositions:

  • 29 + 31466759 = 31466788
  • 131 + 31466657 = 31466788
  • 191 + 31466597 = 31466788
  • 239 + 31466549 = 31466788
  • 401 + 31466387 = 31466788
  • 461 + 31466327 = 31466788
  • 809 + 31465979 = 31466788
  • 1031 + 31465757 = 31466788

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.37.36.

Address
1.224.37.36
Class
public
IPv4-mapped IPv6
::ffff:1.224.37.36

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

Position in π

The digit sequence 31466788 first appears in π at position 844,111 of the decimal expansion (the 844,111ordinal-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.
