Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140240, here are decompositions:
- 3 + 140237 = 140240
- 13 + 140227 = 140240
- 19 + 140221 = 140240
- 43 + 140197 = 140240
- 73 + 140167 = 140240
- 97 + 140143 = 140240
- 241 + 139999 = 140240
- 271 + 139969 = 140240
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 140,240 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 140240 first appears in π at position 685,411 of the decimal expansion (the 685,411ordinal-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.
