Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142162, here are decompositions:
- 3 + 142159 = 142162
- 5 + 142157 = 142162
- 11 + 142151 = 142162
- 101 + 142061 = 142162
- 113 + 142049 = 142162
- 131 + 142031 = 142162
- 191 + 141971 = 142162
- 311 + 141851 = 142162
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 142,162 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 142162 first appears in π at position 490,025 of the decimal expansion (the 490,025ordinal-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.
