Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120342, here are decompositions:
- 11 + 120331 = 120342
- 23 + 120319 = 120342
- 43 + 120299 = 120342
- 59 + 120283 = 120342
- 109 + 120233 = 120342
- 149 + 120193 = 120342
- 179 + 120163 = 120342
- 239 + 120103 = 120342
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 120,342 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 120342 first appears in π at position 579,287 of the decimal expansion (the 579,287ordinal-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.
