Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170864, here are decompositions:
- 7 + 170857 = 170864
- 13 + 170851 = 170864
- 37 + 170827 = 170864
- 97 + 170767 = 170864
- 103 + 170761 = 170864
- 157 + 170707 = 170864
- 163 + 170701 = 170864
- 223 + 170641 = 170864
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 170,864 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 170864 first appears in π at position 426,232 of the decimal expansion (the 426,232ordinal-suffix:nd 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.
