Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121404, here are decompositions:
- 37 + 121367 = 121404
- 47 + 121357 = 121404
- 53 + 121351 = 121404
- 61 + 121343 = 121404
- 71 + 121333 = 121404
- 83 + 121321 = 121404
- 113 + 121291 = 121404
- 137 + 121267 = 121404
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 121,404 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 121404 first appears in π at position 890,047 of the decimal expansion (the 890,047ordinal-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.
