Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167788, here are decompositions:
- 11 + 167777 = 167788
- 17 + 167771 = 167788
- 29 + 167759 = 167788
- 41 + 167747 = 167788
- 59 + 167729 = 167788
- 167 + 167621 = 167788
- 191 + 167597 = 167788
- 251 + 167537 = 167788
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 167,788 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 167788 first appears in π at position 445,660 of the decimal expansion (the 445,660ordinal-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.
