Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146566, here are decompositions:
- 3 + 146563 = 146566
- 23 + 146543 = 146566
- 47 + 146519 = 146566
- 53 + 146513 = 146566
- 89 + 146477 = 146566
- 149 + 146417 = 146566
- 197 + 146369 = 146566
- 257 + 146309 = 146566
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 146,566 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 146566 first appears in π at position 645,709 of the decimal expansion (the 645,709ordinal-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.
