Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133788, here are decompositions:
- 7 + 133781 = 133788
- 19 + 133769 = 133788
- 71 + 133717 = 133788
- 79 + 133709 = 133788
- 97 + 133691 = 133788
- 131 + 133657 = 133788
- 139 + 133649 = 133788
- 157 + 133631 = 133788
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 133,788 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 133788 first appears in π at position 45,108 of the decimal expansion (the 45,108ordinal-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.
