Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167990, here are decompositions:
- 3 + 167987 = 167990
- 19 + 167971 = 167990
- 37 + 167953 = 167990
- 73 + 167917 = 167990
- 79 + 167911 = 167990
- 103 + 167887 = 167990
- 127 + 167863 = 167990
- 181 + 167809 = 167990
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 167,990 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 167990 first appears in π at position 736,790 of the decimal expansion (the 736,790ordinal-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.
