Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171204, here are decompositions:
- 37 + 171167 = 171204
- 41 + 171163 = 171204
- 43 + 171161 = 171204
- 73 + 171131 = 171204
- 101 + 171103 = 171204
- 113 + 171091 = 171204
- 127 + 171077 = 171204
- 151 + 171053 = 171204
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 171,204 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 171204 first appears in π at position 734,467 of the decimal expansion (the 734,467ordinal-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.
