Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133406, here are decompositions:
- 3 + 133403 = 133406
- 19 + 133387 = 133406
- 79 + 133327 = 133406
- 103 + 133303 = 133406
- 127 + 133279 = 133406
- 193 + 133213 = 133406
- 223 + 133183 = 133406
- 337 + 133069 = 133406
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 133,406 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 133406 first appears in π at position 316,745 of the decimal expansion (the 316,745ordinal-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.
