Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140940, here are decompositions:
- 11 + 140929 = 140940
- 31 + 140909 = 140940
- 43 + 140897 = 140940
- 47 + 140893 = 140940
- 71 + 140869 = 140940
- 73 + 140867 = 140940
- 101 + 140839 = 140940
- 103 + 140837 = 140940
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 140,940 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 140940 first appears in π at position 552,901 of the decimal expansion (the 552,901ordinal-suffix:st 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.
