Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133242, here are decompositions:
- 29 + 133213 = 133242
- 41 + 133201 = 133242
- 59 + 133183 = 133242
- 73 + 133169 = 133242
- 89 + 133153 = 133242
- 139 + 133103 = 133242
- 173 + 133069 = 133242
- 191 + 133051 = 133242
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 133,242 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 133242 first appears in π at position 419,097 of the decimal expansion (the 419,097ordinal-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.
