Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173240, here are decompositions:
- 31 + 173209 = 173240
- 103 + 173137 = 173240
- 181 + 173059 = 173240
- 241 + 172999 = 173240
- 271 + 172969 = 173240
- 307 + 172933 = 173240
- 373 + 172867 = 173240
- 433 + 172807 = 173240
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 173,240 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 173240 first appears in π at position 320,178 of the decimal expansion (the 320,178ordinal-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.
