Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142160, here are decompositions:
- 3 + 142157 = 142160
- 37 + 142123 = 142160
- 61 + 142099 = 142160
- 103 + 142057 = 142160
- 199 + 141961 = 142160
- 223 + 141937 = 142160
- 229 + 141931 = 142160
- 307 + 141853 = 142160
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 142,160 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 142160 first appears in π at position 846,123 of the decimal expansion (the 846,123ordinal-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.
