Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165626, here are decompositions:
- 37 + 165589 = 165626
- 67 + 165559 = 165626
- 73 + 165553 = 165626
- 103 + 165523 = 165626
- 157 + 165469 = 165626
- 163 + 165463 = 165626
- 229 + 165397 = 165626
- 277 + 165349 = 165626
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 165,626 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 165626 first appears in π at position 101,919 of the decimal expansion (the 101,919ordinal-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.
