Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170400, here are decompositions:
- 7 + 170393 = 170400
- 11 + 170389 = 170400
- 17 + 170383 = 170400
- 29 + 170371 = 170400
- 31 + 170369 = 170400
- 37 + 170363 = 170400
- 47 + 170353 = 170400
- 53 + 170347 = 170400
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 170,400 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 170400 first appears in π at position 987,418 of the decimal expansion (the 987,418ordinal-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.
