Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163572, here are decompositions:
- 5 + 163567 = 163572
- 11 + 163561 = 163572
- 29 + 163543 = 163572
- 89 + 163483 = 163572
- 103 + 163469 = 163572
- 139 + 163433 = 163572
- 163 + 163409 = 163572
- 179 + 163393 = 163572
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 163,572 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 163572 first appears in π at position 129,419 of the decimal expansion (the 129,419ordinal-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.
