Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142456, here are decompositions:
- 3 + 142453 = 142456
- 23 + 142433 = 142456
- 29 + 142427 = 142456
- 53 + 142403 = 142456
- 137 + 142319 = 142456
- 233 + 142223 = 142456
- 239 + 142217 = 142456
- 263 + 142193 = 142456
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 142,456 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 142456 first appears in π at position 405,447 of the decimal expansion (the 405,447ordinal-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.
