Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164222, here are decompositions:
- 13 + 164209 = 164222
- 31 + 164191 = 164222
- 73 + 164149 = 164222
- 109 + 164113 = 164222
- 151 + 164071 = 164222
- 199 + 164023 = 164222
- 211 + 164011 = 164222
- 229 + 163993 = 164222
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 164,222 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 164222 first appears in π at position 475,666 of the decimal expansion (the 475,666ordinal-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.
