Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142582, here are decompositions:
- 23 + 142559 = 142582
- 29 + 142553 = 142582
- 53 + 142529 = 142582
- 113 + 142469 = 142582
- 149 + 142433 = 142582
- 179 + 142403 = 142582
- 191 + 142391 = 142582
- 263 + 142319 = 142582
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 142,582 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 142582 first appears in π at position 820,456 of the decimal expansion (the 820,456ordinal-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.
