Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142462, here are decompositions:
- 29 + 142433 = 142462
- 41 + 142421 = 142462
- 59 + 142403 = 142462
- 71 + 142391 = 142462
- 191 + 142271 = 142462
- 239 + 142223 = 142462
- 251 + 142211 = 142462
- 269 + 142193 = 142462
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 142,462 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 142462 first appears in π at position 373,891 of the decimal expansion (the 373,891ordinal-suffix:st 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.
