Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453522, here are decompositions:

  • 59 + 31453463 = 31453522
  • 101 + 31453421 = 31453522
  • 131 + 31453391 = 31453522
  • 239 + 31453283 = 31453522
  • 281 + 31453241 = 31453522
  • 389 + 31453133 = 31453522
  • 719 + 31452803 = 31453522
  • 773 + 31452749 = 31453522

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.241.82.

Address
1.223.241.82
Class
public
IPv4-mapped IPv6
::ffff:1.223.241.82

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

Position in π

The digit sequence 31453522 first appears in π at position 373,098 of the decimal expansion (the 373,098ordinal-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.
