Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133784, here are decompositions:
- 3 + 133781 = 133784
- 61 + 133723 = 133784
- 67 + 133717 = 133784
- 73 + 133711 = 133784
- 127 + 133657 = 133784
- 151 + 133633 = 133784
- 241 + 133543 = 133784
- 337 + 133447 = 133784
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 133,784 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 133784 first appears in π at position 554,393 of the decimal expansion (the 554,393ordinal-suffix:rd 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.
