Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142052, here are decompositions:
- 3 + 142049 = 142052
- 13 + 142039 = 142052
- 61 + 141991 = 142052
- 181 + 141871 = 142052
- 199 + 141853 = 142052
- 223 + 141829 = 142052
- 241 + 141811 = 142052
- 283 + 141769 = 142052
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 142,052 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 142052 first appears in π at position 363,944 of the decimal expansion (the 363,944ordinal-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.
