Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133842, here are decompositions:
- 11 + 133831 = 133842
- 29 + 133813 = 133842
- 31 + 133811 = 133842
- 41 + 133801 = 133842
- 61 + 133781 = 133842
- 73 + 133769 = 133842
- 109 + 133733 = 133842
- 131 + 133711 = 133842
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 133,842 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 133842 first appears in π at position 221,478 of the decimal expansion (the 221,478ordinal-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.
