Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142384, here are decompositions:
- 3 + 142381 = 142384
- 113 + 142271 = 142384
- 167 + 142217 = 142384
- 173 + 142211 = 142384
- 191 + 142193 = 142384
- 227 + 142157 = 142384
- 233 + 142151 = 142384
- 317 + 142067 = 142384
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 142,384 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 142384 first appears in π at position 110,162 of the decimal expansion (the 110,162ordinal-suffix:nd 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.
