Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173722, here are decompositions:
- 23 + 173699 = 173722
- 53 + 173669 = 173722
- 71 + 173651 = 173722
- 149 + 173573 = 173722
- 173 + 173549 = 173722
- 179 + 173543 = 173722
- 191 + 173531 = 173722
- 239 + 173483 = 173722
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 173,722 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 173722 first appears in π at position 159,019 of the decimal expansion (the 159,019ordinal-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.
