Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162664, here are decompositions:
- 23 + 162641 = 162664
- 41 + 162623 = 162664
- 53 + 162611 = 162664
- 71 + 162593 = 162664
- 101 + 162563 = 162664
- 107 + 162557 = 162664
- 137 + 162527 = 162664
- 191 + 162473 = 162664
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 162,664 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 162664 first appears in π at position 588,274 of the decimal expansion (the 588,274ordinal-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.
