Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164224, here are decompositions:
- 23 + 164201 = 164224
- 41 + 164183 = 164224
- 107 + 164117 = 164224
- 131 + 164093 = 164224
- 167 + 164057 = 164224
- 173 + 164051 = 164224
- 227 + 163997 = 164224
- 233 + 163991 = 164224
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 164,224 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 164224 first appears in π at position 62,283 of the decimal expansion (the 62,283ordinal-suffix:rd 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.
