Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142424, here are decompositions:
- 3 + 142421 = 142424
- 43 + 142381 = 142424
- 67 + 142357 = 142424
- 97 + 142327 = 142424
- 127 + 142297 = 142424
- 193 + 142231 = 142424
- 241 + 142183 = 142424
- 313 + 142111 = 142424
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 142,424 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 142424 first appears in π at position 688,370 of the decimal expansion (the 688,370ordinal-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.
