Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121704, here are decompositions:
- 7 + 121697 = 121704
- 17 + 121687 = 121704
- 43 + 121661 = 121704
- 67 + 121637 = 121704
- 71 + 121633 = 121704
- 73 + 121631 = 121704
- 83 + 121621 = 121704
- 97 + 121607 = 121704
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 121,704 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 121704 first appears in π at position 260,122 of the decimal expansion (the 260,122ordinal-suffix:nd 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.
