Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461702, here are decompositions:

  • 5 + 31461697 = 31461702
  • 29 + 31461673 = 31461702
  • 61 + 31461641 = 31461702
  • 131 + 31461571 = 31461702
  • 149 + 31461553 = 31461702
  • 179 + 31461523 = 31461702
  • 353 + 31461349 = 31461702
  • 359 + 31461343 = 31461702

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.17.70.

Address
1.224.17.70
Class
public
IPv4-mapped IPv6
::ffff:1.224.17.70

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

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

Routing number
031461702
Federal Reserve
Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 31461702 first appears in π at position 424,844 of the decimal expansion (the 424,844ordinal-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.
