Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600084, here are decompositions:

  • 23 + 31600061 = 31600084
  • 41 + 31600043 = 31600084
  • 83 + 31600001 = 31600084
  • 107 + 31599977 = 31600084
  • 167 + 31599917 = 31600084
  • 311 + 31599773 = 31600084
  • 317 + 31599767 = 31600084
  • 401 + 31599683 = 31600084

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.45.212.

Address

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.

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 31600084 first appears in π at position 135,161 of the decimal expansion (the 135,161ordinal-suffix:st 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.
