Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163372, here are decompositions:
- 5 + 163367 = 163372
- 113 + 163259 = 163372
- 149 + 163223 = 163372
- 173 + 163199 = 163372
- 179 + 163193 = 163372
- 191 + 163181 = 163372
- 263 + 163109 = 163372
- 311 + 163061 = 163372
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 163,372 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 163372 first appears in π at position 488,574 of the decimal expansion (the 488,574ordinal-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.
