Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84204, here are decompositions:
- 5 + 84199 = 84204
- 13 + 84191 = 84204
- 23 + 84181 = 84204
- 41 + 84163 = 84204
- 61 + 84143 = 84204
- 67 + 84137 = 84204
- 73 + 84131 = 84204
- 83 + 84121 = 84204
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.72.236.

- IPv4-mapped IPv6
- ::ffff:0.1.72.236
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 84204 first appears in π at position 206,303 of the decimal expansion (the 206,303ordinal-suffix:rd 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.
