Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133722, here are decompositions:
- 5 + 133717 = 133722
- 11 + 133711 = 133722
- 13 + 133709 = 133722
- 31 + 133691 = 133722
- 53 + 133669 = 133722
- 73 + 133649 = 133722
- 89 + 133633 = 133722
- 139 + 133583 = 133722
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 133,722 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 133722 first appears in π at position 667,362 of the decimal expansion (the 667,362ordinal-suffix:nd 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.
