Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160664, here are decompositions:
- 13 + 160651 = 160664
- 37 + 160627 = 160664
- 43 + 160621 = 160664
- 61 + 160603 = 160664
- 73 + 160591 = 160664
- 157 + 160507 = 160664
- 181 + 160483 = 160664
- 211 + 160453 = 160664
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 160,664 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 160664 first appears in π at position 96,832 of the decimal expansion (the 96,832ordinal-suffix:nd 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.
