Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142436, here are decompositions:
- 3 + 142433 = 142436
- 67 + 142369 = 142436
- 79 + 142357 = 142436
- 109 + 142327 = 142436
- 139 + 142297 = 142436
- 199 + 142237 = 142436
- 277 + 142159 = 142436
- 313 + 142123 = 142436
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 142,436 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 142436 first appears in π at position 327,566 of the decimal expansion (the 327,566ordinal-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.
