Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1164, here are decompositions:
- 11 + 1153 = 1164
- 13 + 1151 = 1164
- 41 + 1123 = 1164
- 47 + 1117 = 1164
- 61 + 1103 = 1164
- 67 + 1097 = 1164
- 71 + 1093 = 1164
- 73 + 1091 = 1164
Showing the first eight; more decompositions exist.

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 1164 first appears in π at position 22,271 of the decimal expansion (the 22,271ordinal-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.
