Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142466, here are decompositions:
- 13 + 142453 = 142466
- 97 + 142369 = 142466
- 109 + 142357 = 142466
- 139 + 142327 = 142466
- 229 + 142237 = 142466
- 277 + 142189 = 142466
- 283 + 142183 = 142466
- 307 + 142159 = 142466
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 142,466 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 142466 first appears in π at position 135,859 of the decimal expansion (the 135,859ordinal-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.
