Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142046, here are decompositions:
- 7 + 142039 = 142046
- 109 + 141937 = 142046
- 139 + 141907 = 142046
- 193 + 141853 = 142046
- 277 + 141769 = 142046
- 337 + 141709 = 142046
- 349 + 141697 = 142046
- 367 + 141679 = 142046
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 142,046 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 142046 first appears in π at position 58,340 of the decimal expansion (the 58,340ordinal-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.
