Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142082, here are decompositions:
- 43 + 142039 = 142082
- 151 + 141931 = 142082
- 211 + 141871 = 142082
- 229 + 141853 = 142082
- 271 + 141811 = 142082
- 313 + 141769 = 142082
- 373 + 141709 = 142082
- 433 + 141649 = 142082
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 142,082 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 142082 first appears in π at position 271,128 of the decimal expansion (the 271,128ordinal-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.
