Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121504, here are decompositions:
- 3 + 121501 = 121504
- 11 + 121493 = 121504
- 17 + 121487 = 121504
- 83 + 121421 = 121504
- 101 + 121403 = 121504
- 137 + 121367 = 121504
- 191 + 121313 = 121504
- 233 + 121271 = 121504
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 121,504 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 121504 first appears in π at position 746,147 of the decimal expansion (the 746,147ordinal-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.
