Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133072, here are decompositions:
- 3 + 133069 = 133072
- 59 + 133013 = 133072
- 83 + 132989 = 133072
- 101 + 132971 = 133072
- 179 + 132893 = 133072
- 239 + 132833 = 133072
- 311 + 132761 = 133072
- 383 + 132689 = 133072
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 133,072 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 133072 first appears in π at position 24,009 of the decimal expansion (the 24,009ordinal-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.
