Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170520, here are decompositions:
- 11 + 170509 = 170520
- 17 + 170503 = 170520
- 23 + 170497 = 170520
- 37 + 170483 = 170520
- 47 + 170473 = 170520
- 73 + 170447 = 170520
- 79 + 170441 = 170520
- 107 + 170413 = 170520
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 170,520 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 170520 first appears in π at position 43,822 of the decimal expansion (the 43,822ordinal-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.
