Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142006, here are decompositions:
- 47 + 141959 = 142006
- 89 + 141917 = 142006
- 173 + 141833 = 142006
- 233 + 141773 = 142006
- 239 + 141767 = 142006
- 317 + 141689 = 142006
- 353 + 141653 = 142006
- 383 + 141623 = 142006
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 142,006 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 142006 first appears in π at position 781,172 of the decimal expansion (the 781,172ordinal-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.
