Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167660, here are decompositions:
- 19 + 167641 = 167660
- 37 + 167623 = 167660
- 67 + 167593 = 167660
- 139 + 167521 = 167660
- 211 + 167449 = 167660
- 223 + 167437 = 167660
- 331 + 167329 = 167660
- 349 + 167311 = 167660
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 167,660 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 167660 first appears in π at position 568,997 of the decimal expansion (the 568,997ordinal-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.
