Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120684, here are decompositions:
- 7 + 120677 = 120684
- 13 + 120671 = 120684
- 23 + 120661 = 120684
- 37 + 120647 = 120684
- 43 + 120641 = 120684
- 61 + 120623 = 120684
- 97 + 120587 = 120684
- 107 + 120577 = 120684
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 120,684 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 120684 first appears in π at position 386,416 of the decimal expansion (the 386,416ordinal-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.
