Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163142, here are decompositions:
- 13 + 163129 = 163142
- 79 + 163063 = 163142
- 139 + 163003 = 163142
- 241 + 162901 = 163142
- 283 + 162859 = 163142
- 313 + 162829 = 163142
- 433 + 162709 = 163142
- 439 + 162703 = 163142
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 163,142 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163142 first appears in π at position 615,377 of the decimal expansion (the 615,377ordinal-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.
