Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143140, here are decompositions:
- 3 + 143137 = 143140
- 29 + 143111 = 143140
- 47 + 143093 = 143140
- 167 + 142973 = 143140
- 191 + 142949 = 143140
- 233 + 142907 = 143140
- 269 + 142871 = 143140
- 353 + 142787 = 143140
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 143,140 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 143140 first appears in π at position 618,815 of the decimal expansion (the 618,815ordinal-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.
