Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164216, here are decompositions:
- 7 + 164209 = 164216
- 43 + 164173 = 164216
- 67 + 164149 = 164216
- 103 + 164113 = 164216
- 127 + 164089 = 164216
- 193 + 164023 = 164216
- 223 + 163993 = 164216
- 229 + 163987 = 164216
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 164,216 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 164216 first appears in π at position 136,570 of the decimal expansion (the 136,570ordinal-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.
