Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160172, here are decompositions:
- 3 + 160169 = 160172
- 13 + 160159 = 160172
- 31 + 160141 = 160172
- 79 + 160093 = 160172
- 139 + 160033 = 160172
- 163 + 160009 = 160172
- 193 + 159979 = 160172
- 241 + 159931 = 160172
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 160,172 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 160172 first appears in π at position 121,005 of the decimal expansion (the 121,005ordinal-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.
