Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140842, here are decompositions:
- 3 + 140839 = 140842
- 5 + 140837 = 140842
- 11 + 140831 = 140842
- 29 + 140813 = 140842
- 83 + 140759 = 140842
- 101 + 140741 = 140842
- 113 + 140729 = 140842
- 179 + 140663 = 140842
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 140,842 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 140842 first appears in π at position 140,650 of the decimal expansion (the 140,650ordinal-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.
