Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133478, here are decompositions:
- 31 + 133447 = 133478
- 61 + 133417 = 133478
- 127 + 133351 = 133478
- 151 + 133327 = 133478
- 157 + 133321 = 133478
- 199 + 133279 = 133478
- 277 + 133201 = 133478
- 409 + 133069 = 133478
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 133,478 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 133478 first appears in π at position 391,090 of the decimal expansion (the 391,090ordinal-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.
