Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142634, here are decompositions:
- 43 + 142591 = 142634
- 61 + 142573 = 142634
- 67 + 142567 = 142634
- 97 + 142537 = 142634
- 181 + 142453 = 142634
- 277 + 142357 = 142634
- 307 + 142327 = 142634
- 337 + 142297 = 142634
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 142,634 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 142634 first appears in π at position 675,151 of the decimal expansion (the 675,151ordinal-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.
