Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3748, here are decompositions:
- 29 + 3719 = 3748
- 47 + 3701 = 3748
- 71 + 3677 = 3748
- 89 + 3659 = 3748
- 131 + 3617 = 3748
- 167 + 3581 = 3748
- 191 + 3557 = 3748
- 257 + 3491 = 3748
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.14.164.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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.
The digit sequence 3748 first appears in π at position 14,257 of the decimal expansion (the 14,257ordinal-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.
