Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165426, here are decompositions:
- 29 + 165397 = 165426
- 43 + 165383 = 165426
- 47 + 165379 = 165426
- 59 + 165367 = 165426
- 83 + 165343 = 165426
- 109 + 165317 = 165426
- 113 + 165313 = 165426
- 139 + 165287 = 165426
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 165,426 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 165426 first appears in π at position 19,500 of the decimal expansion (the 19,500ordinal-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.
