Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167648, here are decompositions:
- 7 + 167641 = 167648
- 37 + 167611 = 167648
- 127 + 167521 = 167648
- 157 + 167491 = 167648
- 199 + 167449 = 167648
- 211 + 167437 = 167648
- 241 + 167407 = 167648
- 307 + 167341 = 167648
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 167,648 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 167648 first appears in π at position 142,866 of the decimal expansion (the 142,866ordinal-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.
