Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133942, here are decompositions:
- 23 + 133919 = 133942
- 89 + 133853 = 133942
- 131 + 133811 = 133942
- 173 + 133769 = 133942
- 233 + 133709 = 133942
- 251 + 133691 = 133942
- 269 + 133673 = 133942
- 293 + 133649 = 133942
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 133,942 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 133942 first appears in π at position 148,548 of the decimal expansion (the 148,548ordinal-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.
