Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121964, here are decompositions:
- 13 + 121951 = 121964
- 43 + 121921 = 121964
- 97 + 121867 = 121964
- 277 + 121687 = 121964
- 331 + 121633 = 121964
- 373 + 121591 = 121964
- 433 + 121531 = 121964
- 457 + 121507 = 121964
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 121,964 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 121964 first appears in π at position 502,166 of the decimal expansion (the 502,166ordinal-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.
