Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133742, here are decompositions:
- 19 + 133723 = 133742
- 31 + 133711 = 133742
- 73 + 133669 = 133742
- 109 + 133633 = 133742
- 199 + 133543 = 133742
- 223 + 133519 = 133742
- 421 + 133321 = 133742
- 439 + 133303 = 133742
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 133,742 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 133742 first appears in π at position 385,314 of the decimal expansion (the 385,314ordinal-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.
