Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170940, here are decompositions:
- 13 + 170927 = 170940
- 19 + 170921 = 170940
- 41 + 170899 = 170940
- 53 + 170887 = 170940
- 59 + 170881 = 170940
- 67 + 170873 = 170940
- 83 + 170857 = 170940
- 89 + 170851 = 170940
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 170,940 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 170940 first appears in π at position 48,615 of the decimal expansion (the 48,615ordinal-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.
