Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133420, here are decompositions:
- 3 + 133417 = 133420
- 17 + 133403 = 133420
- 29 + 133391 = 133420
- 41 + 133379 = 133420
- 71 + 133349 = 133420
- 83 + 133337 = 133420
- 101 + 133319 = 133420
- 137 + 133283 = 133420
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 133,420 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 133420 first appears in π at position 466,530 of the decimal expansion (the 466,530ordinal-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.
