Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142464, here are decompositions:
- 11 + 142453 = 142464
- 31 + 142433 = 142464
- 37 + 142427 = 142464
- 43 + 142421 = 142464
- 61 + 142403 = 142464
- 73 + 142391 = 142464
- 83 + 142381 = 142464
- 107 + 142357 = 142464
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 142,464 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 142464 first appears in π at position 193,619 of the decimal expansion (the 193,619ordinal-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.
