Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143424, here are decompositions:
- 5 + 143419 = 143424
- 11 + 143413 = 143424
- 23 + 143401 = 143424
- 37 + 143387 = 143424
- 67 + 143357 = 143424
- 137 + 143287 = 143424
- 163 + 143261 = 143424
- 167 + 143257 = 143424
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 143,424 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 143424 first appears in π at position 687,066 of the decimal expansion (the 687,066ordinal-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.
