Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133584, here are decompositions:
- 13 + 133571 = 133584
- 41 + 133543 = 133584
- 43 + 133541 = 133584
- 103 + 133481 = 133584
- 137 + 133447 = 133584
- 167 + 133417 = 133584
- 181 + 133403 = 133584
- 193 + 133391 = 133584
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 133,584 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 133584 first appears in π at position 663,114 of the decimal expansion (the 663,114ordinal-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.
