Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173472, here are decompositions:
- 41 + 173431 = 173472
- 43 + 173429 = 173472
- 113 + 173359 = 173472
- 163 + 173309 = 173472
- 179 + 173293 = 173472
- 181 + 173291 = 173472
- 199 + 173273 = 173472
- 223 + 173249 = 173472
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 173,472 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 173472 first appears in π at position 149,124 of the decimal expansion (the 149,124ordinal-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.
