Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503466, here are decompositions:

  • 23 + 31503443 = 31503466
  • 257 + 31503209 = 31503466
  • 263 + 31503203 = 31503466
  • 347 + 31503119 = 31503466
  • 359 + 31503107 = 31503466
  • 503 + 31502963 = 31503466
  • 569 + 31502897 = 31503466
  • 977 + 31502489 = 31503466

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.180.106.

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.

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 31503466 first appears in π at position 138,340 of the decimal expansion (the 138,340ordinal-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.
