Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148564, here are decompositions:
- 47 + 148517 = 148564
- 107 + 148457 = 148564
- 197 + 148367 = 148564
- 233 + 148331 = 148564
- 263 + 148301 = 148564
- 491 + 148073 = 148564
- 503 + 148061 = 148564
- 587 + 147977 = 148564
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 148,564 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 148564 first appears in π at position 977,836 of the decimal expansion (the 977,836ordinal-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.
