Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170644, here are decompositions:
- 3 + 170641 = 170644
- 11 + 170633 = 170644
- 17 + 170627 = 170644
- 41 + 170603 = 170644
- 107 + 170537 = 170644
- 197 + 170447 = 170644
- 251 + 170393 = 170644
- 281 + 170363 = 170644
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 170,644 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 170644 first appears in π at position 867,090 of the decimal expansion (the 867,090ordinal-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.
