Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73040, here are decompositions:
- 3 + 73037 = 73040
- 31 + 73009 = 73040
- 43 + 72997 = 73040
- 67 + 72973 = 73040
- 103 + 72937 = 73040
- 109 + 72931 = 73040
- 139 + 72901 = 73040
- 151 + 72889 = 73040
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 73040 first appears in π at position 67,647 of the decimal expansion (the 67,647ordinal-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.
