Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167988, here are decompositions:
- 17 + 167971 = 167988
- 71 + 167917 = 167988
- 89 + 167899 = 167988
- 97 + 167891 = 167988
- 101 + 167887 = 167988
- 109 + 167879 = 167988
- 127 + 167861 = 167988
- 179 + 167809 = 167988
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 167,988 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 167988 first appears in π at position 293,501 of the decimal expansion (the 293,501ordinal-suffix:st 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.
