Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146572, here are decompositions:
- 29 + 146543 = 146572
- 53 + 146519 = 146572
- 59 + 146513 = 146572
- 149 + 146423 = 146572
- 191 + 146381 = 146572
- 263 + 146309 = 146572
- 281 + 146291 = 146572
- 359 + 146213 = 146572
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 146,572 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 146572 first appears in π at position 33,676 of the decimal expansion (the 33,676ordinal-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.
