Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162426, here are decompositions:
- 7 + 162419 = 162426
- 13 + 162413 = 162426
- 37 + 162389 = 162426
- 67 + 162359 = 162426
- 83 + 162343 = 162426
- 137 + 162289 = 162426
- 139 + 162287 = 162426
- 149 + 162277 = 162426
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 162,426 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 162426 first appears in π at position 774,253 of the decimal expansion (the 774,253ordinal-suffix:rd 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.
