Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120842, here are decompositions:
- 13 + 120829 = 120842
- 19 + 120823 = 120842
- 31 + 120811 = 120842
- 79 + 120763 = 120842
- 103 + 120739 = 120842
- 151 + 120691 = 120842
- 181 + 120661 = 120842
- 223 + 120619 = 120842
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 120,842 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 120842 first appears in π at position 246,288 of the decimal expansion (the 246,288ordinal-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.
