Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61984, here are decompositions:
- 3 + 61981 = 61984
- 5 + 61979 = 61984
- 17 + 61967 = 61984
- 23 + 61961 = 61984
- 113 + 61871 = 61984
- 227 + 61757 = 61984
- 233 + 61751 = 61984
- 281 + 61703 = 61984
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.242.32.

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 61984 first appears in π at position 39,325 of the decimal expansion (the 39,325ordinal-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.
