Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163724, here are decompositions:
- 97 + 163627 = 163724
- 103 + 163621 = 163724
- 151 + 163573 = 163724
- 157 + 163567 = 163724
- 163 + 163561 = 163724
- 181 + 163543 = 163724
- 241 + 163483 = 163724
- 307 + 163417 = 163724
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 163,724 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163724 first appears in π at position 369,007 of the decimal expansion (the 369,007ordinal-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.
