Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167222, here are decompositions:
- 31 + 167191 = 167222
- 73 + 167149 = 167222
- 103 + 167119 = 167222
- 109 + 167113 = 167222
- 151 + 167071 = 167222
- 199 + 167023 = 167222
- 313 + 166909 = 167222
- 373 + 166849 = 167222
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 167,222 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 167222 first appears in π at position 919,166 of the decimal expansion (the 919,166ordinal-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.
