Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161024, here are decompositions:
- 7 + 161017 = 161024
- 43 + 160981 = 161024
- 163 + 160861 = 161024
- 211 + 160813 = 161024
- 271 + 160753 = 161024
- 313 + 160711 = 161024
- 337 + 160687 = 161024
- 373 + 160651 = 161024
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 161,024 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 161024 first appears in π at position 569,389 of the decimal expansion (the 569,389ordinal-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.
