Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167646, here are decompositions:
- 5 + 167641 = 167646
- 13 + 167633 = 167646
- 19 + 167627 = 167646
- 23 + 167623 = 167646
- 53 + 167593 = 167646
- 103 + 167543 = 167646
- 109 + 167537 = 167646
- 163 + 167483 = 167646
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 167,646 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 167646 first appears in π at position 851,679 of the decimal expansion (the 851,679ordinal-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.
