Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67166, here are decompositions:
- 13 + 67153 = 67166
- 37 + 67129 = 67166
- 109 + 67057 = 67166
- 163 + 67003 = 67166
- 193 + 66973 = 67166
- 223 + 66943 = 67166
- 277 + 66889 = 67166
- 283 + 66883 = 67166
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 67166 first appears in π at position 99,846 of the decimal expansion (the 99,846ordinal-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.
