Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121464, here are decompositions:
- 11 + 121453 = 121464
- 17 + 121447 = 121464
- 23 + 121441 = 121464
- 43 + 121421 = 121464
- 61 + 121403 = 121464
- 97 + 121367 = 121464
- 107 + 121357 = 121464
- 113 + 121351 = 121464
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 121,464 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 121464 first appears in π at position 435,337 of the decimal expansion (the 435,337ordinal-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.
